When set_colorpairs() is called, no files have been loaded yet, so
no syntaxes will have been loaded yet either. Thus it is pointless
to run through the list of available syntaxes.
Its major function is to find an applicable syntax, if there is any.
And if the syntax hasn't been used before, to prime its color pairs.
Also, reshuffle a line to be able to elide an #ifdef.
Bind the toggling of a bookmark to <Alt+Insert>, and the jumping to the
previous and next bookmark to <Alt+PageUp> and <Alt+PageDown>, so that
these functions are available by default.

With the 'bookmark' function, the user can place a bookmark on any
line in the buffer. Multiple lines can be bookmarked in this way.
With 'prevbookmark' and 'nextbookmark', the user can then easily
return to the bookmarked lines. The search for a bookmark wraps
around, as if start and end of buffer are connected.
[However, in this implementation, when a bookmarked line is deleted,
the bookmark is deleted too. This is undesirable. Also, when such
a deleted line is pasted elsewhere, the bookmark reappears with it,
and when pasted multiple times, the bookmark will be there as many
times. This is thoroughly undesirable. These behaviors will be
changed in a later commit.]
A bookmark is not yet visible in any way.

Even though a user would never type ^J to start a new line, accept it
as a synonym of <Enter> (^M) in a bracketed paste, because apparently
bash accepts it as a synonym too.
This works around https://savannah.gnu.org/bugs/?58010.
The old address has become invalid, and probably does not have enough
room for the write, thus causing a crash.
This fixes https://savannah.gnu.org/bugs/?57858.
Bug existed since commit 8625609c from two days ago.
Not doing it characterwise saves a reallocation, a memmove(), several
checks, and an update_undo() for each character over one.
This has been tested by temporarily setting 'bracketed_paste = FALSE'
instead of 'bracketed_paste = TRUE' in convert_sequence() in winio.c,
and then pasting stuff into nano.
And before the buffer size is adjusted, so that the add_undo()
doesn't need to correct the stored former size of the buffer.
This will allow the injection of multiple characters at once,
in the next commit.
Using straightforward comparisons is clearer and faster and shorter.
Again, note that this does not filter out 0x7F (DEL). But that is
okay, as that code will never be returned from get_kbinput().
The few calls of the injection routines that had 'filtering' set to
TRUE have already filtered out ASCII control codes earlier on. And
in the case of injecting a completion, this completion only contains
word-forming characters -- and if the user somehow added a control
code to the word-forming characters, then nano should NOT filter it
out, so in fact that setting of 'filtering' to TRUE was mistaken.
Note that this filtering did not filter out 0x7F (DEL). But that is
fine: it should not occur in the input stream at that point anyway,
as it gets translated to either KEY_DC or KEY_BACKSPACE earlier in
the keyboard parsing routines.
When at startup the user presses Cancel at the "open anyway?" prompt,
cancel the whole startup: quit. But when the user answers No, just
skip the file and continue starting up.
The 'prev' and 'next' links get assigned to immediately after the
call of copy_node(). And anyway, it does not make sense to link
a copied node to the predecessor and successor of its original.
Also slightly regroup some lines.
