When parsing a line and a column number, of course the found values
need to be passed back, otherwise it would be pointless to parse them.

input: don't drop the first byte when user starts typing during loading
...
Precalculation of the multiline color data can be cut short when the
user is impatient and starts typing. But this would drop the first
byte of whatever was typed -- not nice when it was just plain text,
but surprising and worse when the first keystroke was a command.
This fixes https://savannah.gnu.org/bugs/?48388 .

color: push the resets further when start and end match are equal
...
When for a multiline syntax-coloring rule the starting regex matches at
the exact same spot as the ending regex, do a second round of resets, so
that reevaluation starts further back and gets a few more things right.
This mildly fixes https://savannah.gnu.org/bugs/?47420 .

tweaks: rename a variable to be more accurate
...
When we get a ^J as verbatim input, it is not possible to include it
into the file buffer or the prompt answer, because this would mean
adding an encoded null to the buffer or answer, and that is not what
the user intended. One option would have been to simply ignore a ^J
in verbatim input. But the choice has been made to act the same way
as when the ^J (0x0A) is found in the file data: start a new line.
That is the same response as to the Enter key, yes -- but the code
for the Enter key is ^M (0x0D), not ^J. So, to be more precise,
rename the relevant variable from 'got_enter' to 'got_newline'.

...
When the user tab-completed a name at the Go To Directory prompt, this
name will end in a slash. Remove this slash, so the name can be found
in the file list (where directory names don't include the final slash).
This fixes http://savannah.gnu.org/bugs/?48353 .

screen: don't check for every character whether there is still enough space

Just allocate ample space up front and thus discard the delaying 'if' for

The representation of DEL (0x7F) continues as ^?.

tweaks: try to distinguish between keystrokes and characters
...
Keystrokes are single integers (aided by the flags meta_key and
func_key) but in the input stream they can be encoded as escape
sequences (a series of bytes). Characters are values in byte
range, but in UTF-8 one character can consist of multiple bytes.
Also rename two variables, because the secondary input buffer
that they refer to contains only characters (mostly just one),
never any shortcuts; and there are too many "kbinput" already.
