8455251c35 files: revert the previous commit, as the extra warning is annoying 
It also erroneously left the succeeding prompt on the screen.

416386edcd files: alert the user afterward when an overwritten file is being edited 
(The ideal behavior would be that nano would warn the user beforehand,
before the file that is being edited by someone else gets overwritten,
but that would require many more changes.  So... just give a helpful
warning -- that's already better than it was.)

497f126bb2 files: write a lock file also for a new file and when the name changed 
(When the new or changed name is that of an existing file AND this
file is being edited by some other editor (or nano itself), then the
behavior is rather strange: nano asks whether to continue, but the
file has already been overwritten and there is nothing the user can
do to cancel or revert things.  A later commit should improve this.)

This fixes https://savannah.gnu.org/bugs/?47975,
and fixes https://savannah.gnu.org/bugs/?53883.

68c3aaf2df softwrap: when switching to another buffer, re-align the starting column 
When we switch to another buffer, the window may have been resized
since we were last in this buffer, so make sure that 'firstcolumn'
gets a fitting value.

This fixes https://savannah.gnu.org/bugs/?56991.

Bug existed since version 2.8.0, since the softwrap overhaul.

fa88fcc8f2 tweaks: rename a function, and elide a parameter that is always NULL 
After the previous change, all remaining calls of parse_mbchar() have
NULL as their third parameter.  So, drop that parameter and remove the
chunk of code that handles it.  Also rename the function, as there are
already too many functions that start with "parse".

3a0ac428ba tweaks: remove a redundant check for an existing emergency file 
This case is caught (by O_EXCL) later on, at the appropriate moment:
when the file is created.

Also, this removes a superfluous lstat() for each temporary file.

5390f96900 files: distinguish between read error and write error when prepending 
This fixes https://savannah.gnu.org/bugs/?57066.

Bug existed in this form since version 2.4.3 -- in older versions
it segfaulted.

a6365707c0 tweaks: remove the superfluous closing of a file descriptor

4e40ec057e tweaks: elide an unneeded check when making a backup 
When making a backup, we can be certain that the relevant file
is not a temporary file, so 'stream' will necessarily be NULL.

022cc084a7 files: when opening a file for copying, it should NOT be created 
Weird bug.  The first occurrence is probably never hit because the
existing file has been tentatively opened fourteen lines earlier,
but that looks superfluous: double work.  And the second occurrence
will not be hit because the temp file is unlikely to have disappeared.

0f98466e2f tweaks: adjust the indentation after the previous change 
Also, don't bother assigning the stream pointer of the existing file
to variable 'f', as it gets overwritten right away by the pointer of
the temp file.

40c067133a tweaks: remove two superfluous conditions when prepending 
When prepending, we cannot be writing to a temp file,
so 'stream' (and thus 'f') will necessarily be NULL.

3347682fd0 tweaks: remove a pointless updating of the title bar 
A possible change in filename won't be pushed to the screen until a
doupdate() is done, and that won't happen until nano is waiting for
a keystroke again.  So... just let it be.

34170611d3 restored feature: a per-syntax 'fixer' command that processes the buffer 
The command can be used to run some kind of formatter or corrector or
arranging tool on the buffer.  By default the command is bound to M-F.
The formatter/corrector/arranging program must be non-interactive.
