Because "lightnormal" sounds strange, and can have unexpected effects.
This fixes https://savannah.gnu.org/bugs/?60668.
Bug existed since version 2.9.5, since the name "normal" was introduced.
When using +/ or +?, any minor feedback should be cleared,
to not distract from the highligted search result.
This fixes https://savannah.gnu.org/bugs/?60669.
Bug existed since version 5.5, commit b86f7868,
since the manner of grading status-bar messages changed.
After a "+" only c, r, C, and R are valid characters,
and only when immediately followed by / or ?.
This fixes https://savannah.gnu.org/bugs/?60667.
Bug existed since version 4.4, commit 2326bf6,
since searching at startup with +/ or +? was introduced.
The "^_" has always been poorly legible (the underscore melting into
the bottom of the terminal) and difficult to type (Shift+Ctrl+minus).
The "^/" is both more readable and easier to type.
In terminal emulators, "^/" is shown, but on a Linux console "^-",
as ^/ does a backspace in the default console key mapping.
Also, allow using "^-" when rebinding ^_ in a nanorc file.
This addresses https://savannah.gnu.org/bugs/?57393.
Simply adding the number of bytes in the quoting part is not entirely
correct, but... currently the indenting and commenting routines also
assume that the whitespace and commenting characters that are added or
removed are single-byte characters... It will require another patch
to make this all fully correct, but for the default configuration
(and probably most other cases) the current fix will work fine.
This fixes https://savannah.gnu.org/bugs/?60605.
Bug existed since version 4.4, commit 8fce33af from two years ago,

When on a one-row terminal a message gets automatically "dropped"
after a few moments, the subsequent waiting for a keystroke should
not think that there is still a message on the status bar.
This fixes https://savannah.gnu.org/bugs/?60591.
Bug existed since commit 8d974cd2 from two days ago.
When there is just one row and there is a message, it is not a good idea
to draw the contents of the buffer as it would overwrite the message.
This fixes https://savannah.gnu.org/bugs/?60582.
Bug existed since version 2.7.0, since nano allows very flat terminals,
and was made worse by commit 2cf28f9d from yesterday.
Redraw the content of the edit window (for the undone final completion)
before pushing out the "No further matches" message, so that the latter
will not get overwritten by the buffer content -- in case the terminal
has just one row.
This fixes https://savannah.gnu.org/bugs/?60581.
Bug existed since commit 2cf28f9d from yesterday.
Only important error messages (ALERT) and information that the user
requested (^C, M-D) should stay put until the next keystroke. Other
messages should be overwritten by the text of the buffer after just
a few moments, to make a one-row terminal slightly more friendly.
This addresses https://savannah.gnu.org/bugs/?60570.
When showing a message on the status bar, the cursor should be off.
This fixes https://savannah.gnu.org/bugs/?60510.
Bug existed since version 2.7.0, since nano allows very flat terminals.
When there is just one row, the text to be edited needs to be shown
there, not some meta information about the cursor position.
This fixes https://savannah.gnu.org/bugs/?60563.
Bug existed since version 2.7.0, since nano allows very flat terminals.
Since version 5.6, commit 76742cc1, nano highlights the search match,
which means that the screen gets refreshed anyhow, so this specific
refresh for a one-row terminal is no longer needed.
This prevents read() from returning unexpectedly and causing a crash.
This fixes https://savannah.gnu.org/bugs/?60537.

Bug existed since version 2.4.2, since the handling of SIGWINCH changed.
That is: call edit_refresh() right away, to prevent the edit_refresh()
in the main loop from overwriting the status-bar message.

Bug existed since version 5.6, commit 76742cc1.
When there is just one row, the user wants to see text on this row,
not a bar with some meta info.
This fixes https://savannah.gnu.org/bugs/?60508.
Bug existed since version 5.5, since the minibar was introduced
with commit d31cc373.
In many places a carriage return is not valid whitespace and should
thus not be colored as such. In some of these places a vertical tab
or form feed is maybe valid whitespace, but it would be ugly or even
wrong to color them because they are not part of the subsequent
comment or keyword.
This fixes https://savannah.gnu.org/bugs/?60456.
Changes:
1. There may be zero spaces between 'include' and '<...>'.
2. Blanks and '=' may occur inside '<...>' but '>' may not.
3. There must be at least one character inside '<...>'.

Since commits b0209374 and 1c010d8e from a month ago, nano does not use
mblen() and mbtowc() any more, so there is no need to check for their
presence.
Instead, add a check for iswalpha(), which we do use.
This reduces startup time by seven percent (when using the standard set
of syntaxes) when opening just one file that doesn't match any syntax,
and more than ten percent when opening multiple files. It takes some
extra memory, but... not wasting CPU cycles is more important.
This addresses https://savannah.gnu.org/bugs/?56433.
When undoing several actions, it is possible for the line at the top
of the screen to be removed, leaving 'edittop' pointing to a structure
that has been freed. Soon after, 'edittop' is referenced to determine
whether the cursor is offscreen... Prevent this invalid reference by
stepping 'edittop' one line back in that special case. This changes
the normal centering behavior of Undo when the cursor goes offscreen,
but... so be it.
When a single node is deleted, it is always possible to step one line
back, because a buffer contains always at least one line (even though
maybe empty), so if the current line could be deleted, there must be
one before it (when at the top of the screen).
This fixes https://savannah.gnu.org/bugs/?60436.
Bug existed since version 2.3.3, commit 60815461,
since undoing does not always center the cursor.
Since two commits ago, the position of the indicator shows the position
of the viewport relative to the full buffer in terms of actual lines,
not of visual chunks (to avoid excessive computation). But the size of
the indicator stayed constant, as if it always covered as many lines as
the edit window has rows. But the latter will not be the case when
softwrapping occurs. Therefore, when softwrapping, compute how many
actual lines are visible in the viewport, and adjust the size of the
indicator accordingly.
Whenever softwrap was toggled on or line numbers were toggled on/off or
the window was resized, the extra rows per line needed to be recomputed
for ALL the lines. For large files with many long lines this was too
costly.
(This change causes the indicator to have an incorrect size when there
are many softwrapped chunks onscreen, but that will be addressed later.)
This fixes https://savannah.gnu.org/bugs/?60429.
Problem existed since version 5.0, since the indicator was introduced.
