The cursor can function as a reading aid for people with poor vision.

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.
As the help viewer is almost a normal buffer, commands that make sense
-- like searching backwards, and searching the previous occurrence --
should work in the help viewer too.
In addition, show all Search commands prominently in the help lines of
the help viewer, so that users are likely to notice them and will maybe
infer that they work in the editor itself too.
This fixes https://savannah.gnu.org/bugs/?54368.

In the preceding commit, open_buffer() was changed so that it gets
told whether to load into a new buffer or not, so it is no longer
needed to convey this information through a flag.
When just scrolling and the cursor does not need to change position
(that is: it is not on the first or last row of the edit window),
then edit_scroll() has handled everything and there is no need to
additionally redraw anything or update 'placewewant'.
Help texts are shown without any line numbers, so the full width
of the screen should be used to display the text.
This fixes https://savannah.gnu.org/bugs/?53308.
When a fragment of help text does not contain any whitespace that
we can wrap at, just advance the pointer, because returning zero
would mean we stay forever at the same place: nano would hang.
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.
The basic idea is that the cursor is always off, except when it needs
to be on: when waiting for text input, and in a few other cases: when
something was searched and found in the help viewer, and in the file
browser when option -g is in effect.

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.
And hide the cursor again as soon as the user scrolls.
Achieve this through making the 'didfind' variable global.
Also, remove a superfluous call of wnoutrefresh(), as bottombars()
already does that.

Things have morphed over time and display_buffer() no longer actually
displays the buffer -- it just displays the title bar, precalculates
the multiline color info, and schedules a refresh of the edit window.
We should measure the length of each /translated/ shortcut description,
not of the original English one.
This fixes https://savannah.gnu.org/bugs/?50899.
