^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.

Date and version are updated to match each release, so the user does
not have to wonder whether the man page really describes the binary.

Also remove a bit of superfluous markup.

This is no longer accurate.

So that these functions have bindings by default, and easy bindings.
Add them to the help viewer too, so that searching backward becomes
possible there.

The new option 'set selectedcolor' applies to marked text, to the
currently selected file in the file browser, and to the highlighted
match during interactive search-and-replace.

And reword them too, so that it is clearer what the mechanism is
for determining which syntax to use for a file.

Rename the corresponding rc-file option too, of course.

And in the bargain improve some mark-up here and there.

And rewrap the feature toggles, so that a title does not start
a sentence.

And refer backward instead of forward.

In nano, -a is only effective when also -$ is given, so this will
not conflict with Pico since Pico does not know the -$ option.

Extend get_softwrap_breakpoint() to break softwrapped lines on
whitespace when a flag is set.  This flag is controlled by the new
rcfile option "atblanks".  The '>' characters marking two-column
characters at the edge of the screen are disabled when it's on.

If get_softwrap_breakpoint() can't find whitespace in screen range, it
will break the line on the screen edge.  (In this case, a blank can be
on the last column of the screen, but text can't, so that a blank on the
last column doesn't become invisible and possibly break the display.)

Also remove the backslashes from the two syntaxes that contained them.

This completes the fix for https://savannah.gnu.org/bugs/?51370.

For the man page, encode them properly, and for the Info stuff,
just set the right document encoding.

This fixes https://savannah.gnu.org/bugs/?51369.

The comment marker is not «."» but «.\"», which requires three
backslashes to specify.  Also adjust the documentation.

Also, use proper mark-up for the examples.

The dash doesn't have to be the first non-option argument: it can
be anywhere among the filenames -- there can even be multiple ones
(but don't mention this explicitly).

Especially: get rid of the "Up: (dir)" link that points nowhere.

Also, add a horizontal line before the final Table of Contents.

This fixes https://savannah.gnu.org/bugs/?51208.
