When curses gives no code for Ctrl+Shift+Delete, do not fall back
to KEY_BACKSPACE, because then ^H and/or <Backspace> get bound to
'cutwordleft'.
This fixes https://savannah.gnu.org/bugs/?54642.
Bug was introduced with version 3.0, commit e6429e78.
That is, wait with deleting words until they start under cursor,
so the user can see which word is goin to be eaten, and join lines
only when the cursor already sits at the edge of a line.
On FreeBSD and NetBSD (when reached through ssh from a Linux machine)
this has the absurd effect of making <Ctrl+Backspace> do a 'cutwordleft'
by default, out of the box, without needing any rebindings. Weird, but
wonderful, because the ideal behavior.
Also ensure that <Shift+Delete> always does a Backspace.
This makes that we have the following set of "congruent" keys:
<Tab> moves text to the right,
<Shift+Tab> moves text to the left,
<Delete> "eats" a character to the right,
<Shift+Delete> "eats" a character to the left,
<Ctrl+Delete> "eats" a word to the right,
<Shift+Ctrl+Delete> "eats" a word to the left.
Also, don't partially color "..." as an operator, because it isn't,
and color also the unary operator "#".

Adding "[abc]*" does not restrict the recognized header line in any way.
Also, improve the header-line regex for shell scripts, because it should
not match "barunscript" (for example).
If find_paragraph() detects that we're not in a paragraph, it moves
forward a paragraph and then backward to that paragraph's beginning.
Make it check whether we're in a paragraph before moving backward
(since there might not *be* any more paragraphs), to prevent going
forth-and-back and never reaching the end of the buffer.

These are available in the menus where they are relevant: the Write-Out
and the Insert menu, respectively. Having them duplicated in the main
menu is inconsistent and eats precious keystrokes. (Sorry, Chris.)
When 'inhelp' is true, there are at least two buffers open: an
edit buffer and the help-text buffer.
And bottombars() already does a full refresh of the bottom window.
And restore the cursor to this position when redoing the cut+insert.
Also remove two unneeded conditions.
This fully fixes https://savannah.gnu.org/bugs/?54466.
When piping the buffer (or the marked region) to an external command,
we should wait not only for the external command to terminate but also
for the data-sending process, so that it will release its resources.
This fixes https://savannah.gnu.org/bugs/?54499.

When undoing/redoing an alternate spell check (of the entire file
or of a backwards marked region), put the cursor back where it was
when the spell check was invoked/finished.
This fixes https://savannah.gnu.org/bugs/?54466.
On a Linux VT, refuse to start when there are errors in a nanorc file,
so that the messages no longer get overwritten -- which prevented the
user from seeing and reading them.
This fixes https://savannah.gnu.org/bugs/?54442.
Since the last version, the user can filter an entire buffer through
an external command. This external command can also be a formatting
program, so there is no longer any need for this specific and special
formatter command.
