Also, reshuffle a case, to put the short one first and lose a line.

Instead of assuming that the entire contents of the keybuffer are an
escape sequence (even if this is far longer than any escape sequence
can be), remove from the keybuffer only those integers that actually
constituted a sequence, valid or invalid.

Trimming trailing spaces is good, but we should not trim the space
(or tab or other blank) that the user just typed and that caused the
hard-wrapping to occur.

It will be reallocated soon enough when the size increases again.

Also remove an unneeded nulling.

The verbosity "hid" the really relevant information:
filename, line number, and the error message.

Valid values and other details can be found in the manual pages.

When the palette is getting initialized, it is too late to send any
error messages about the rcfile options to standard error.

When we're just searching, we do want to report the occurrence at
the cursor (after coming full circle) as a match, so that we can
mention that this is the only occurrence.  When replacing, we do
not want to replace this match twice.

And reword some things about translations and Unicode support.

So the result could be used during RC-file reading.

Also drop an old debugging fragment.

There shouldn't be two separate variables (but with the same name) that
count the number of digits seen.  Fuse them into a single static var.

This fixes https://savannah.gnu.org/bugs/?52863.

Use the same method as in parse_verbatim_kbinput() for Unicode input.
