Trying to determine which syntax to apply with the help of libmagic
can be a somewhat time-consuming and yet often still fruitless affair.
Therefore using libmagic should not be the default; it should require
an option to tell nano to try using libmagic when it can't determine
the applicable syntax from the file's name or first line.
This is better than having a --nomagic option (and using libmagic by
default), because when the user has 'set nomagic' in their nanorc or
--nomagic in their alias, then switching the use of libmagic back on
is troublesome. But with --magic (and not using libmagic by default),
when nano fails to recognize a file, it is a simple ^X, add -! to the
command line, and restart.
The short form of the option is -! because we have run out of letters.

With --stateflags (short form: -%) or 'set stateflags', nano reserves
the righthand end of the title bar not for showing "Modified" but for
showing the state of auto-indentation (I), the mark (M), the breaking
of long lines (L), macro recording (R), and softwrapping (S).
When the buffer is modified, this is indicated with a star (*) after
the file name (shown in the center of the title bar).
This fulfills https://savannah.gnu.org/bugs/?57953.

Typing ^H (by default equivalent to Backspace) at the start of the file
is not useful. When it happens, assume that the user is new and tried
to ask for Help. So... explain what the caret and the "M-" in the help
lines mean.
Also, to keep menu items nicely grouped in the Main, Search, Replace,
and Goto menus, reorder a few items when no help is available.

When nano reports "Unbound key" or "Unknown sequence", this message
should stay onscreen only for the relevant keystroke, not for any
succeeding keystroke.

Bug existed since before version 2.0.6.
Slang fails to translate the longer sequences, and then truncates
these sequences to just four bytes, effectively destroying them.
Therefore, when built with --with-slang, always activate --raw-sequences.
This avoids https://savannah.gnu.org/bugs/?49771.
Bug was visible since version 2.5.0, since bindings
for Ctrl+Left/Ctrl+Right were added.
In this way, any message that is on the status bar after the search
will be a response to this search and not some leftover.
This fixes https://savannah.gnu.org/bugs/?59109.
(This effectively reverts commit ba47abb4 from two days ago, but it
groups things better. It makes an unnecessary call to bottombars()
for M-Q and M-W, but this hardly matters: searching in a help text
does not need to be efficient.)
This fixes https://savannah.gnu.org/bugs/?59108.

The tiny version is about being small, not about convenience features
that hardly anyone uses anyway.
Also exclude the description of the "+line[,column]" feature -- it is
unneeded verbosity.
This addresses https://savannah.gnu.org/bugs/?59101.
The cursor would disappear after any message on the status bar --
for example, also when M-W is typed and nothing is found -- so the
mitigation trick needs to be performed in statusline() itself.
This addresses https://savannah.gnu.org/bugs/?59091.
In the tiny version (built with Slang and running on Debian's bterm)
the Ctrl+Left/Ctrl+Right keystrokes do not work. When the terminal
is wide enough, instead of showing ^B + ^F for Backward and Forward
(which are unneeded because the unmodified arrow keys work fine),
show M-B + M-N for Prev Word and Next Word.
(Listing ^Space and M-Space instead would cause "Prev Word" and
"Next Word" to be truncated. They are weird keystrokes anyway.)
Also, list M-Q + M-W for "Previous" and "Next" next to "Where Is"
and "Replace", so that it is slightly clearer what they refer to.
For some reason, when running a tiny nano built with Slang on the bterm
of a Debian installer image, the cursor disappears when certain things
are written to the status bar. Make the cursor reappear by rewriting
the two help lines with dummy items (and then rewriting it again with
the normal menu in the central loop). Of course, this does not help
when the user uses -x or --nohelp to suppress the help lines, but at
least in the default setup the cursor doesn't get hidden now and then.
This mitigates https://savannah.gnu.org/bugs/?59091.
Bug existed since before version 2.2.4.
