When the current filename is equal to the filename of the buffer,
then clear the filename, because the chances that the user wants
to append or prepend a file to itself are practically nil.
This fulfills https://savannah.gnu.org/bugs/?61243.
The keystrokes are not listed, but should work like
they do in a normal, editable buffer.
This fixes https://savannah.gnu.org/bugs/?61274.
Bug existed since version 4.0, commit bc98dbca.
The functions to_first_file() and to_last_file() can get called from
do_statusbar_input(), which is called indirectly from do_prompt(),
and are expected to make the corresponding adjustment.
This fixes https://savannah.gnu.org/bugs/?61273.
Bug existed since version 5.0, commit 07c1ac90.
Some Yaml files use path names and sometimes version numbers as keys,
even though / and . are not officially in the character set allowed
for key names (just like underscore is not), as far as I understand.
Also, do not colorize any backslash escapes as invalid
because some of them occur sometimes in value strings.
Also, colorize only the valid double-exclamation tags.
This avoids an unused and misleading assignment that might make
someone think the incremented variable will be used again.

Perl keys can contain a double colon. And unspaced colons occur
quite regularly in values (URLs, IPv6 addresses, and the like)
and should not be colored as if they were an error.
The calls of write_file() in do_spell() and do_formatter() write out
a temporary file -- such a file does not have an 'openfile' record,
so setting 'annotate' to TRUE was pointless. Using the correct value
for this parameter allows dropping two conditions in write_file().
And when 'exiting' is TRUE and --save-on-exit is in effect, it is
slightly wasteful to stat() the written file and store the info in
its 'openfile' record as the buffer will be closed directly after.
So, now the only place where 'annotate' is TRUE is when writing out
the full buffer to a normally named file.
First, we don't want the writing of an emergency file to be interrupted
by the user. But more important: the routine for restoring the handler
also disables SIGINT, which would leave the terminal with a non-working
Ctrl+C.
Saving an emergency file calls write_file() in a unique manner: with
thefile == NULL, fullbuffer == FALSE (even though the entire buffer
will be saved, of course) and tmp == TRUE (even though it is not a
temporary file, as it will persist after nano exits). But in fact
we want the handler for Ctrl+C installed only for normal files, not
for temporary files and not for emergency files -- the user should
not be able to interrupt the writing of those.
This fixes https://savannah.gnu.org/bugs/?61237.
Bug existed since version 4.3, commit 8550c6bd.
Trying to prepend would hang nano until some other process writes
something to the fifo.
This fixes https://savannah.gnu.org/bugs/?61236.
Bug existed since before version 2.2.4.
Curses cannot function if not informed via TERM which type of terminal
is being used. As many terminals are mostly compatible with a VT220,
falling back to "vt220" when TERM is unset has a good chance of giving
the user a usable nano, instead of simply failing.
(Falling back to "vt100" is not good as it contains padding delays.)
This partially addresses https://bugs.debian.org/991982.
In the terminal font that I use nowadays (that deals well with
combining characters), the normal diamond exceeded the boundaries
of a single cell and thus partly covered the first character of
the relevant line.
When a segment of text is extracted, copy any anchors that it has
into the cutbuffer, so that they get saved in the undo item, so that
an undo will put these anchors back on the lines where they were,
instead of leaving an inherited anchor at the top of the segment.
And when text is pasted, clear any anchors in it, so that they will
not travel nor multiply.
This fixes https://savannah.gnu.org/bugs/?61162.
Bug existed since version 5.0, since anchors were introduced.
On most terminals "bold" also makes the relevant text lighter (or just
makes it lighter, like on a Linux console). Only some terminals allow
the user to switch this coupling of bold to light off.

It should be "bold,white,red" instead of "brightwhite,red"
because "bright" is deprecated and not documented.

That is: pause a little to jolt the user, and then leave the message
on the status bar.

Bug existed since version 4.8, commit 416386ed.
This fixes https://savannah.gnu.org/bugs/?61146
Bug existed since version 2.3.2, since --locking was introduced,
and continued to exist since version 4.8 despite commit 497f126b
claiming to have fixed it.
