Since version 6.0, with option --zero, the edit window can cover
the whole terminal. Make use of this also for the credits crawl.
Also, shorten and quicken the crawl a bit, and make it start always
on the bottom row, instead of (for mysterious reasons) one row higher
when the terminal has an odd number of rows.
Furthermore, don't put back the key the user typed to stop the crawl.
Instead of starting always from the top of the buffer, start at the
current line, as it is quite likely to be near the target line.
(Since the previous commit we're assuming that openfile->current is
always valid, so we might as well make use of this assumption.)
Also, rename a parameter to make its meaning more explicit.
After undoing an <Enter> or redoing a line join, it is likely that the
"eaten" and freed line was the current line. In fact, goto_line_posx()
should not refer to it any more, but... accommodate for this and just
set openfile->current to a valid value before calling goto_line_posx().
This fixes https://savannah.gnu.org/bugs/?62952.
Bug existed since version 6.3, commit eea3e1f0.
Checking for the literal ^N, ^Q, and ^Y before checking for do_toggle
and full_refresh made it impossible to rebind any of those keystrokes
to these two functions. (Not that anyone would want this, but...)
Problem existed since version 4.3, commits 341601e1 and 82aea04c.
This allows specifying bindable functions in a string bind by name
instead of by the literal control code or escape sequence to which
they are bound, which makes for a much more readable string bind,
and also allows specifying functions that are not bound to any key.
The opening brace, {, is made into a special symbol inside a string
bind, and each literal occurrence there needs to be escaped as {{}.
This fulfills https://savannah.gnu.org/bugs/?61692.

This makes that the three options that change the default layout
of the interface (--stateflags, --minibar, --zero) come last.
Also, sort the option letters into a consistent order in the code.
(That 'also_the_last' now gets reset to FALSE whenever the cursor moves
to a different line is fine -- it is redundant when the mark is off, but
it does no harm.)
It was silly to check again specifically for <Del> and <Bsp> after
any possible keystroke had been handled. It was an anomaly.
This makes the tail of do_deletion() similar to the tail of inject().
(That sometimes the current line is redrawn twice is acceptable -- how
often does one type <Backspace> while having Shift-selected something?
Normally one wouldn't, because it would cancel the selection, so it's
fine to accept some inefficiency for this case.)
The checking for all functions that are marked as not-okay-for-view-mode
was excessive and unneeded. It had been inherited from commit d47d8cd4
from thirteen years ago, and was never verified for correctness.
This addresses the main part of https://savannah.gnu.org/bugs/?62903.
The linter has been marked as NOVIEW since it was introduced in 2.3.3.
But that was a mistake, as the tool does not change the buffer contents.
This addresses a minor part of https://savannah.gnu.org/bugs/?62903.
This is especially meant to avoid dereferences of 'shortcut' after its
linked function has been executed, because in an upcoming commit this
execution may have freed the shortcut's structure.
(For symmetry, make the same change also in do_statusbar_input(), even
though it is not needed there.)
This addresses one part of https://savannah.gnu.org/bugs/?62899.
The only menus that are accessible in view mode are WhereIs, Insert,
WhereIsFile, GoToDirectory, and Help. In the WhereIs menu, the only
keystroke that is not allowed in view mode (^R) is caught explicitly.
In the other four menus, all available shortcuts are permissible in
view mode, so... there is no need to check them at execution time.
(The ^R keystroke in the WhereIs menu is still shown in view mode
so as not to upset the pairing of the subsequent shortcuts.)
Since commit 63f2be7a from four years ago, view mode always sets
multibuffer mode, allowing ^R (Insert) to be invoked. But the
user is then not allowed to switch multibuffer mode off, so...
don't show the toggle.
This allows one to complete also words that are present in other files
(when these are open in other buffers).
This fulfills https://savannah.gnu.org/bugs/?61691.

When confirm_margin() first sets the margin needed for the requested
line numbers, also then it needs to keep 'focusing' TRUE. Only when
actually toggling --linenumbers ON (from a zero margin to something)
should focusing be suppressed, in order to obtain smooth scrolling
when the cursor is pushed off-screen.
This fixes https://savannah.gnu.org/bugs/?62885.
Bug existed since version 4.4, since the search-at-startup feature
was introduced.
In many keyboard layouts M-< and M-> are awkward to type (in a Spanish
layout, for example: Alt+Shift+AltGr+Z and Alt+Shift+AltGr+X when there
is no LSGT key), whereas M-, and M-. are simple two-key keystrokes in
most Latin-script layouts. So, show M-,/M-. before showing M-</M->.
Also, make a condition more precise, to not show M-Left and M-Right in
the tiny version, when those shortcuts are not understood.
