In path names and file names, 0x0A means an embedded newline and
should be shown as ^J, but in anything related to the file's data,
0x0A is an encoded NUL and should be displayed as ^@.
So... switch mode at the two main entry points into the "file system"
(reading in a file, and writing out a file), and also when drawing the
titlebar. Switch back to the default mode in the main loop.
This fixes https://savannah.gnu.org/bugs/?49893.
Decode 0x0A bytes to 0x00 when saving the search history, and encode
them again when reading the file back in, to prevent nano from hanging
or aborting when encountering 0x00 on a line by itself.
After updating the color palette, the corresponding new window content
should be drawn immediately, before some other part of the code calls
doupdate(), to prevent the old content being shown in the new colors.
This fixes https://savannah.gnu.org/bugs/?49912.

A filename might contain spaces, so we can't look for the numbers
(the second and third elements) starting from the head of the line
-- we have to start at the tail and work backward.
This fixes https://savannah.gnu.org/bugs/?49879.
So they will not break a line in the positionlog file in two.
(Strangely, the reading in of such a log file already decodes
nulls back into newlines.)
This fixes https://savannah.gnu.org/bugs/?49877.
Most full paths are needed only temporarily and will be freed within
milliseconds. Only 'full_operating_dir' and 'backup_dir' continue to
exist for the whole current session. Any partition, too, will soon be
unpartitioned, so the extra reallocation is just a waste of time.
The functions read() and fwrite() take size_t, not ssize_t.
And line numbers in the file should be displayed as a long type instead
of an int, since the effective type of ssize_t is not int, but long.
Achieve this by reusing the code that gives feedback when trying to
save a buffer while using --tempfile and the file has no name yet.
This fixes https://savannah.gnu.org/bugs/?48622.
If it would, the returned file descriptor would make nano crash,
because the corresponding stream has not been opened. And when
returning zero instead (as the code did originally), nano would
open an empty buffer, although it claims to be reading the file.
In short: I think this is a leftover of an attempted fix of
https://savannah.gnu.org/bugs/?25297, from commit 2823c99.
Add the keycodes and routines to allow the user to forego setting the
mark explicitly (with M-A / ^6) and instead quickly select a few words
or lines by holding down Shift together with the movement keys.
(Some combinations with Shift are swallowed by some terminal emulators.
To work around some of those, the combinations Shift+Alt+Left/Right work
as Shift+Home/End and Shift+Alt+Up/Down work as Shift+PageUp/PageDown.)
