In this way a single keystroke can produce a fragment of text or a
series of commands, or a mix of the two.  It is like a prerecorded
macro.

This fulfills https://savannah.gnu.org/bugs/?52931.

And one for me, for the much changed keyboard stuff.

Also, actually add the long option --trimblanks to the table.

So the result could be used during RC-file reading.

Each leading tab is converted to two tabs, and any leading four spaces
is converted to one tab.  The intended tab size (for keeping most lines
within 80 columns) is now four.

When unindenting/uncommenting affected the bottom line of the marked
region, keep affecting this line also during subsequent consecutive
indenting/commenting.

The function get_keycode() should never return zero -- it should
return either the code from ncurses or the given fallback code.

This fixes https://savannah.gnu.org/bugs/?52682.

In this way we can delete things on the current line with ^K (after
Shift-selecting some text) without nano misdetecting a line change,

This fully fixes https://savannah.gnu.org/bugs/?52576.

Only when the cursor has moved off of the currrent line do we stop
prepending wrapped words to the next line.

This partially fixes https://savannah.gnu.org/bugs/?52576.

To get rid of two double negatives.

This fixes http://savannah.gnu.org/bugs/?52523.

When some or all edits have been undone, and the user starts to make
new edits, the old part of the undo stack is discarded, but this does
not mean that the undo stack doesn't go back to the very beginning.

This really fixes https://savannah.gnu.org/bugs/?52504.

The softmark is now only cancelled when the cursor is moved without
Shift being held, not for things like ^L (Refresh), ^C (Position),
or ^G (Help).

This addresses https://savannah.gnu.org/bugs/?52470.

The pointer not being NULL is enough indication that the mark is set.

Also, rename the pointer from 'mark_begin' to simply 'mark', since
the former is kind of pleonastic.

Also, remove an unneeded pair of braces.

Whenever a buffer is closed, check whether the positions file on disk
was modified, and if so, reload it.  Then update the position for the
closed buffer and write out the positions file to disk.

The function get_key_buffer() assumes waiting_mode = TRUE, but stdin
can be in non-blocking mode when a program (before nano) turned stdin
to non-blocking mode and did not change it back (possibly because it
crashed).  So, explicitly set stdin to blocking mode at startup.

When not finding a .nanorc file in the user's home directory, nano will
look for a nanorc file in $XDG_CONFIG_HOME and in the ~/.config/nano/
fallback directory.  And when not finding a .nano/ subdir in the user's
home directory, nano will look for (or create) the history files in
$XDG_DATA_HOME or in the ~/.local/share/nano/ fallback directory.

This is a partial implementation of the XDG Base Directory Specification:
https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html

,
for the purpose of reducing the clutter in a user's home directory, and
to make it easier to back up just the configuration files.

If the user uses a single version of nano, they have no need for
--quiet.  If they do sometimes use an older version and don't want
to see the warnings, they can use 2>/dev/null (they could make an
alias for that and put it before the call of nano).
