When executing a command, it is now possible to pipe the entire buffer
(or the marked region, if anything is marked) to the external command.
The output from the command replaces the buffer (or the marked region),
or goes to a new buffer.
This fulfills https://savannah.gnu.org/bugs/?28993,
and fulfills https://savannah.gnu.org/bugs/?53041.

When the file has just been read, it is in the state that it has
on disk, so there is nothing to undo.
This fixes https://savannah.gnu.org/bugs/?53387.
That is, call display_string() just on the filename, not on the rest
of the prompt text.
This fixes https://savannah.gnu.org/bugs/?52967.

Each leading tab is converted to two tabs, and any leading four spaces
is converted to one tab. The intended tab size (for keeping most lines
within 80 columns) is now four.
Unset the "Modified" marker only at the point where the file was last
saved -- if there is such a point, because it can be missing when the
undo stack was discarded.
This fixes https://savannah.gnu.org/bugs/?52689.

This also means that no question needs to be asked when exiting.

The pointer not being NULL is enough indication that the mark is set.
Also, rename the pointer from 'mark_begin' to simply 'mark', since
the former is kind of pleonastic.
In the tiny version, do_prompt() will now have an extra NULL
parameter, which will cost maybe twenty extra bytes of code.
That is acceptable when it saves thirty lines in the source.
The key sequence ^R ^X M-F <Enter> would cause nano to abort, because
it would try to add an empty string to a history list. (Furthermore,
simply don't execute an empty command, because it is pointless.)

^S will be the first thing people will try for saving a file,
and ^Q is somewhat mnemonic because it is to the left of ^W:
it searches backward.
Make these keystrokes available also in the tiny version.
Before writing a file out, nano should check that the file on disk
hasn't been modified since it was read -- not only for the normal
"Write Out" action (^O), but also for "Save File" (future ^S) and
for "Save and Exit" (^X when --tempfile is used).
When writing fails and --tempfile is in effect, don't go on to prompt
for a file name; instead let the user decide what she wants to do.
This fixes https://savannah.gnu.org/bugs/?51040.

When multiple files were open and [x/n] was being shown in the title
bar, don't show nano's name and version number when just one buffer
remains open, but show [1/1] instead. It is less surprising.
