Commit 36ec76a made the wrong change: after a tab that did not list any
file names on the screen, a refresh /is/ needed, because a previous tab
might have listed things on the screen. But at the end of the prompt,
it is not necessary to refresh the edit window if things were listed,
because the window will be refreshed anyway after reading in a file.
Use 'slash' to point at a possible slash, use 'filename' just to
point at the real file name, and use 'wasdirname' just to point at
the dir's name before expanding it in order to be able to free it.
Also, remove two superfluous asserts: 'dirname' cannot be NULL
because it has just been mallocstrcpy'd, and checking 'num_matches'
is pointless as it would crash on the next statement anyway.
This is a remnant from 2001, when things were different. Now, there
is no need to refresh the edit window when tabbing produced no list.
When it did produce a list, it is cleared off later.
If for some reason opening the spell-checked or formatted file fails,
don't throw away the current contents of the buffer.
(It should also give proper feedback about the failure, but we'll leave
that for some other time.)
Also, store the input character earlier, so we don't have to use len - 1.
Furthermore, len increments in steps of 1, so it cannot pass the value of
bufx unnoticed, so use a comparison for equality.
Most of the time NO_CONVERT will not be set, the number of lines will
not be zero, and the format of the file will be zero. Rearrange the
conditions so that they will evaluate as FALSE as soon as possible.
Index i follows almost synchronously the value of len. Since we're
adding characters to the intermediate buffer always only at the end,
just use len as the index.
Until now (when not leaving files unconverted), nano would fumble and
drop the final carriage return of a Mac file, and would thus treat the
last line of such a file as an unterminated line and prepend it to the
current line of the buffer. Correct that, and delete the dead piece
of code that was meant to do this.
This fixes https://savannah.gnu.org/bugs/?47716.
When we don't set edittop in read_line(), we don't need to readjust it in
read_file(), because in that particular case it will still be pointing at
current. And since fileptr is a new, freshly created line, it can never
be equal to filebot, so there is no point in comparing them.
If more than one line was inserted at the beginning of the file, leave it
up to the screen handling to set edittop to what it should be.
Move the setting of fileage a bit down, to its sister setting: the line
at current gets "connected" either to the top-of-file pointer or to the
last line of the inserted file.
(This change will be made superfluous when we start using gnulib.)
This prevents getcwd() from failing on Android and thus completes the
fix for https://savannah.gnu.org/bugs/index.php?47659.

Doing a chdir("..") will not fail when the root directory is reached,
and when getcwd() keeps failing too, we have no way of knowing when
to stop. So, simply limit the number of attempted chdirs, to avoid
getting into an endless loop.
This avoids the hang in https://savannah.gnu.org/bugs/index.php?47659.

Instead of allocating a fixed amount of 128 bytes, which will overflow

- Change do_prompt and get_prompt_line to pass meta_key and func_key
so the calling program can DTRT when it calsl get_shortcut. In

and toggles and sc for shortcut keys, old 'shortcut' and 'toggles' structs are
gone. The current implementation has a bunch of broken stuff (some of which is
documented in BUGS). Updated nanorc.5 with some mostly complete documentation
on configuring.

odd behavior (e.g. adding a copy of the entire match to the middle of
the line instead of just the uncompleted part of the match)
