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.

A forward slash does not need to be escaped, and the backslash itself
should not be escaped: it serves to escape the star, to make it literal.
Also, remove a stray end-of-line anchor ($).
When there is just one match when <Tab> is pressed, and this match
is a directory, then a slash is added to 'shared', overwriting the
terminating NUL character. So, strcpy() cannot be used for copying
this 'shared' string, but strncpy() is needed, and the result needs
to be NUL terminated afterward.
This fixes https://savannah.gnu.org/bugs/?58826.
Bug existed since commit b0f56398 from eleven days ago.
The whiles are unneeded because the result of get_input() can
never be NULL when in waiting mode -- and only when searching
for something are we NOT in waiting mode.
<Ctrl+numeric slash> does not invoke Go To Line, so it is fitting
that <Esc> <Esc> <numeric slash> does neither. If some user does
want the double escape plus slash to work, they can use --raw.
(Also, if someone really uses <Esc> <Esc> <numeric slash>, they
probably also type the desired line number on the numeric keypad,
and for that to work they needed to have NumLock engaged, and in
that case the double escape plus slash will work fine.)
(Getting rid of this numeric-slash support makes the three-escapes
case very similar to the one-escape case, allowing the first to be
folded into the latter in the next commit.)
With the two situations that need to preserve the escape counter
now returning directly, the resetting of this counter can happen
at the end of each case block.
The escape-parsing routine nowadays returns FOREIGN_SEQUENCE instead
of ERR when encountering an unknown sequence. So, with the two cases
that demand ERR now handled directly, there is no need to check for
ERR any more.
There is no need to reset the digit counter (because this counter
matters only when the escape counter equals two) -- resetting the
escape counter is enough.
