Include the shortcut for 'Uncut' into most menus, and add an uncut
function for the status bar, so that it becomes possible to paste
the first line of the cutbuffer at any text-input prompt.
This fulfills https://savannah.gnu.org/bugs/?48501.

Assume that a linter line that contains an actual error message or
warning includes a colon followed by a space -- something that that
opening message from a modern gcc lacks.
Human column numbers are one-based, whereas x positions are zero-based.
Converting from the one to the other involves subtracting one. But when
the linter message does not provide a column number, the latter defaults
to zero. Catch that case and change the number to one.

Commit 28beb3f added the 'forreal' parameter to prevent spotlight() from
placing the cursor wrongly due to an invalid placewewant. However, since
the variable-width softwrap overhaul (specifically, since commit 8490f4a),
place_the_cursor() no longer checks placewewant, so the parameter is no
longer needed.
Furthermore, dropping 'forreal' and thus always setting current_y won't
affect the operation of spotlight(), since the only functions that use
spotlight() (do_replace_loop() and do_int_spell_fix()) both call
edit_refresh() beforehand, which means that current_y will already
have been set to the value it will be set to again.
The function place_the_cursor() assumes that the viewport is up to date,
i.e., that current is in range of edittop. When uncutting or inserting,
however, place_the_cursor() gets called on the out-of-date viewport
first, and then a screen refresh is scheduled (which would put the
viewport up to date). This is backwards: the refresh should come before
the cursor placement, and the only reason it works anyway is because the
cap on the number of chunks to move backward papers over the problem by
keeping current_y in screen range regardless.
Fix this properly by simply setting current_y to the bottom row of the
screen instead of calling place_the_cursor(). This value of current_y
is only ever used when in smooth scrolling mode and the insertion (or
paste) pushed the cursor offscreen. In other situations, this value is
overridden when place_the_cursor() gets called after a screen refresh.
After that fix, the cap on the number of chunks to move backward is no
longer needed.
When not using --smooth (nor 'set smooth'), and a line near or beyond
the end-of-file is addressed with the + command-line argument, then
center the cursor, just like Pico does -- so in the default mode,
nano is again more like Pico.
This partially addresses https://savannah.gnu.org/bugs/?51489.
Counting the added number of rows is only relevant when inserting
a file into the current buffer. So don't waste time counting when
it's not needed.

Since commit 8490f4ac, get_edge_and_target() depends on an up-to-date
current_x. So: make sure current_x is updated when we move to the
top left of the screen to start a non-smooth PageUp or PageDown.

For some reason, when returning from suspension, SLang will produce
either a clipped error code (0xFF instead of 0xFFFF, when returning
from an externally induced suspension), or it will clip the code of
first subsequent keystroke to a single byte (when returning from a
normal, in-editor suspension: ^Z).
Side-step this by ignoring the clipped error code, and by using an
undefined control code as the first fake keystroke. Ignoring the
clipped error code is not possible when using a single-byte locale,
otherwise the user would not be able to type the character with
code 0xFF (although it could still be entered with Esc Esc 255).
This fixes https://savannah.gnu.org/bugs/?51477.
The help lines need to be redrawn one step after a justification
(whether it has been undone or not, to replace "Unjustify" with
"Uncut" again for ^U), and after switching buffers (to update a
possibly changed tag for ^T).
This fixes https://savannah.gnu.org/bugs/?51455.
The parameter 'cols', that indicates how many columns to indent or
unindent, is changed to be always positive, so the check for being
negative can go. And it could never be zero anyway.
