Using --zap or -Z on the command line, or 'set zap' in a nanorc file,
makes the <Bsp> and <Del> keys erase selected text (a marked region)
as they do in some other editors, and without affecting the cutbuffer.
This fulfills https://savannah.gnu.org/bugs/?54837.

This function allows the user to "make space": annihilating lines or
regions while keeping intact for pasting the stuff in the cutbuffer
that was cut or copied earlier.

Rename not only the bindable functions, but more importantly reword the
tags that are shown for ^P and ^N in the help lines: "Older" / "Newer",
because these are clearer and not awkward abbreviations.
It would result in having both <Delete> and <Backspace> behaving as
Backspace, which seems senseless -- unless the <Delete> key produces
ASCII DEL and --rebinddelete is needed to make it behave as Delete.
In the latter case it would make more sense if --rebinddelete made
both rebindings: ASCII DEL to Delete and KEY_DC to Backspace, like
it used to be in the distant past, before commit 79a33bb3.
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.)
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.
This makes things symmetrical: ^W starts a forward search, ^Q starts
a backward search, M-W searches the next occurrence forward, and M-Q
searches the next occurrence backward.
The Tabs-To-Spaces toggle is moved to M-O, and thus the More-Space
toggle is no longer bound by default.
Also, consistently refer to Latin letters and ASCII characters
where needed, and document more accepted characters.
This addresses https://savannah.gnu.org/bugs/?54071.
The Alt key together with Shift is a special workaround for when
Shift+PgUp and Shift+PgDn don't work on the user's terminal. But
probably it is more common to use the Ctrl key together with Shift
to select larger pieces of text. So mention this possibility.
Otherwise the first line of a multiline /*...*/-comment would be
seen as quoted and thus *not* as the first line of a paragraph.
In the code, use "/{2}" to prevent the remainder of the line
getting colored as a comment.
In the past, the argument could be either a regex or a literal string,
so the wording was kind of vague. But nowadays we can count on having
regex support (through gnulib), so be more precise in the description.
Since version 2.8.0, nano will use (wnen needed) the regex routines
from gnulib, so mentioning the quotestr for when regex support is
lacking, has been obsolete and pointless for more than a year.
Also, remove some superfluous backslashes, use a non-breaking space
in the texinfo document, and order the regex consistently.
When 'afterends' is set and Ctrl+Right or Shift+Ctrl+Right is pressed,
nano will stop at the ends of words instead of their beginnings.
