When Unicode Input has started (by typing 0 or 1 at the Verbatim Input
"prompt"), and something is typed that is not a hexadecimal digit, then
don't try to enter this character into the buffer but simply report it
as invalid and ignore it. Because most likely the user mistyped and
actually meant to enter a valid hex digit.
This fixes https://savannah.gnu.org/bugs/?58927.
The bug was old -- it existed since at least version 2.0.6.
Just like <Ctrl+Down> goes to the end of the buffer when after the
cursor there are only blank lines.
This fixes https://savannah.gnu.org/bugs/?58921.
Bug existed since version 2.6.2, since <Ctrl+Up/Down> were introduced.
The correct sequences begin with "Esc [" instead. I cannot find in the
histories of VTE and Gnome Terminal when these sequences were corrected.
Also exclude a bug check from the tiny version.
When we get an ESC from the keyboard, it might be the start of an
escape sequence, but the keyboard routines will need a little time
(tens of microseconds, probably) to get these codes to ncurses.
So, when doing verbatim input, pause a moment after an ESC.
This completes the fix for https://savannah.gnu.org/bugs/?58909.
Always interpret ESC followed by BS or DEL as <Alt+Backspace>.
This fixes https://savannah.gnu.org/bugs/?58910.
Bug existed since commit 40b03162 from one week ago,
since M-Bsp was hard-bound to deleting a word backwards.
(This could lead to unwanted behavior when the user wants to enter
a literal escape character (0x1B) while the input is somehow getting
stalled, because then a command keystroke after the M-V <Esc> would
get inserted verbatim too, instead of getting acted upon. But that
is a small price to pay for getting the correct behavior for both
M-V M-Bsp and M-V M-Enter.)
This fixes https://savannah.gnu.org/bugs/?58909.
Bug existed since version 2.6.3, commit 08c51cfd,
but also occurred erratically beforehand.
After commit 59bbc0b8 from five days ago (that made a divergent pipe
failure to be treated in the same way as the other two), this became
possible without having two different pipe-failure messages.
The user had better avoid using the keystroke in a macro, but
when typing directly at a responsive machine there is no problem,
M-[ is a perfectly valid and recognizable keystroke.
This fulfills https://savannah.gnu.org/bugs/?58820.
The make_new_node() function initializes 'extrarows' to a bad value
on purpose, to catch cases like this one where it doesn't get updated
properly.
This fixes https://savannah.gnu.org/bugs/?58890.

Bug existed since version 5.0, since the indicator was introduced.
More generally, after invoking the formatter, the entire buffer should
be cut (to be replaced with the reformatted text) and not just the part
before the mark, because then everything after it would be duplicated.
This fixes https://savannah.gnu.org/bugs/?58879.
Bug existed since version 4.9, commit 19517fc5.
When compiling with GCC 10.1.0 and -O2 -Wall, the strncpy() call
in measured_copy() produced two stringop-truncation warnings.
This addresses https://savannah.gnu.org/bugs/?58861.

Between an endwin() and a doupdate() there should be no calls of
statusline() or statusbar() -- these two functions may be called
only when in curses mode.
This fixes https://savannah.gnu.org/bugs/?58868.
Bug existed since version 4.3, commit 57390cff.
If forking fails, we must first return to curses mode before we can show
an error message on the status bar. (This additionally requires storing
the error number, because doupdate() apparently sets it to zero.)
This fixes https://savannah.gnu.org/bugs/?58864.
Bug existed since version 4.8, commit 61197563.
It jars a bit that it is <Ctrl+Delete> that deletes a word rightward
and <Alt+Backspace> that deletes a word leftward. But it's good to
also have a two-key keystroke bound by default to 'chopwordleft',
and not just the three-key <Ctrl+Shift+Delete>.
This fulfills https://savannah.gnu.org/bugs/?58709.

While ignoring permission errors from fchmod() and fchown() is okay
(since normal users are not always privileged to make such changes),
ignoring also more serious errors (like EIO) is not ideal.
