bc6645f753 tweaks: move two functions to before the ones that call them 2020-03-19 15:12:40 +01:00

c1ca578853 tweaks: unwrap four lines, and use explicit codes where possible 
The explicit codes are slightly faster, and they show the correspondence.

56308b3256 display: keep the help items aligned, by not writing too many characters 
Only for the last item at the end of each of the two help lines there
are sometimes a few extra columns available.  Do not use these extra
columns also for the other help items, because apparently, when wmove()
lands in the second column of a double-width character, it does not
wipe out this character (replacing it with a space) but goes to the
next column instead, causing a misalignment of the text.

This fixes https://savannah.gnu.org/bugs/?57994.

Bug existed since version 1.3.12, commit e806ab84.

2b6924ef6e display: do not show a "[" double-width placeholder when softwrapping 
The placeholder half-duplicates the character that is actually shown
at the beginning of the next row.  When NOT softwrapping, showing a
"[" before the ">" kind of makes sense: to avoid having a gaping gap
there.  But when softwrapping, all characters of the line will be on
the screen (except when going offscreen at the bottom), so there is
no need to show a placeholder for anything.

I imagine that when reading softwrapped Chinese or Japanese text,
things are easier to understand when no characters are shown that
are not actually in the text.

This avoids https://savannah.gnu.org/bugs/?57993.

Bug existed since version 2.8.6, commit 8490f4ac.

01d8b0e15d help: increase the minimum help-text width from 32 to 40 columns 
Getting long words like "Rechtschreibprüfung" broken somewhere in
the middle doesn't look nice.

16f17f3f1b help: do not break a line inside the 17-column keystrokes area 
When the description of a keystroke starts with a very long word,
or when it does not contain any spaces at all (like for Chinese
and Japanese), do not break in the blanks before the description
but instead break IN the description, at the edge of the screen.

In other words: when wrapping a help text, do not consider blanks in
the first 17 columns to be blanks (unless it is a continuation line).

This fixes https://savannah.gnu.org/bugs/?57987.

Bug existed since version 4.8, commit 1486f32d,
when the wrapping of help texts was improved.

3690d60b71 rcfile: rename bindable function 'suspendenable' to 'suspendable' 
The name of a toggle function should match the name of the corresponding
option, like for 'mouse' and 'linenumbers' and 'smarthome' and such.

4dedb1c1b1 moving: do not put the cursor at end-of-line when in a help text 
Keeping the invisible cursor at the left edge avoids any line getting
scrolled horizontally.

This fixes https://savannah.gnu.org/bugs/?57991.

Bug existed since version 2.8.2, since the help texts got generated
and displayed in a different way in order to become searchable.

6ab754676a build: update the conditional placement of the "Go To Line" menu item 
When either only --disable-justify or --disable-speller is used, the
"Go To Line" item should not be placed after the ^C Position item, to
keep the subsequent items (Undo, Redo, and so on) nicely paired.

(Things changed since the Linter is no longer bound to ^T by default.)
