Benno Schulenberg 6b5aff4878 tweaks: put unshifted shortcuts ^6 and M-6 first, instead of ^^ and M-^
The unshifted shortcuts are easier to type, and also less confusing in
my eyes.  Putting them first means they get shown in the help lines,
and get listed first in the ^G help text.

(I would also like to put ^- first instead of ^_ (because the latter
is hard to see when using the default inverse video for shortcuts),
but on several terminal emulators Ctrl+- reduces the font size.)

Benno Schulenberg fb534bada6 bindings: make ^Up/^Down go to first/last row in the file browser
Making ^Up and ^Down go to top and bottom row in the file browser
complements and completes the behavior of ^Left and ^Right.

Benno Schulenberg c01d6a8f74 tweaks: reshuffle the bindings to group things more logically
Put all the movement keys together, in order of ascending stride.

Also, move the Undo/Redo keystrokes further up, so that, when the
user has a somewhat wider terminal than the usual 80 characters,
these keystrokes will be shown -- they are far more interesting
than the ^Y and ^V ones, for which PgUp and PgDn can be used.

David Lawrence Ramsey 812ecaeb0c weeding: remove maxlines and related code
Since all lines can be partially scrolled off the screen now
(except for edittop, which is forthcoming), the maxlines global
variable and its computation mechanism are no longer needed.

David Lawrence Ramsey d8189703b1 tweaks: prepare for improvements to do_home() and do_end()
These improvements will eventually make do_home() and do_end() take
parameters.  Since the global function lists can hold only functions
without parameters, preemptively add do_home_void() and do_end_void(),
and make the global function lists use them.

Hans-Bernhard Broeker 636b7348a6 tweaks: make sure calls to <ctype.h> functions/macros use "unsigned char"
The platform's default char type might be signed, which could cause
problems in 8-bit locales.

This addresses https://savannah.gnu.org/bugs/?50289.

Benno Schulenberg eef7d1047a screen: display byte value 0x0A in the right places as ^@ or as ^J
In path names and file names, 0x0A means an embedded newline and
should be shown as ^J, but in anything related to the file's data,
0x0A is an encoded NUL and should be displayed as ^@.

So... switch mode at the two main entry points into the "file system"
(reading in a file, and writing out a file), and also when drawing the
titlebar.  Switch back to the default mode in the main loop.

This fixes https://savannah.gnu.org/bugs/?49893.

Benno Schulenberg 68a0314500 build: add configure option --disable-wordcomp to disable word completion
(The variable 'pletion_line' is not conditionalized with this option, as
it would become messy.  The compiler will probably be able to elide it.)

When using --enable-tiny, it is not possible to use --enable-wordcomp,
because the word completion function uses the undo system.

Sumedh Pendurkar dca4ab5d8f new feature: complete a fragment to a longer word found in the buffer
Executing the 'complete_a_word' function will search from the start
of the current buffer for entire words that begin with the fragment
that is before the cursor, and will complete this fragment to the
first word that is found.  Each consecutive call of 'complete_a_word'
will search for the next matching word and will complete the fragment
to that.  By default the function is bound to the ^] keystroke.

Benno Schulenberg 382c9d792d new feature: allow text selection by holding Shift with the cursor keys
Add the keycodes and routines to allow the user to forego setting the
mark explicitly (with M-A / ^6) and instead quickly select a few words
or lines by holding down Shift together with the movement keys.

(Some combinations with Shift are swallowed by some terminal emulators.
To work around some of those, the combinations Shift+Alt+Left/Right work
as Shift+Home/End and Shift+Alt+Up/Down work as Shift+PageUp/PageDown.)
