This allows the user to specify which other characters, besides the
default alphanumeric ones, should be considered as part of a word, so
that word operations like Ctrl+Left and Ctrl+Right will pass them by.
Using this option overrides the option --wordbounds.
This fulfills https://savannah.gnu.org/bugs/?47283.
Invalid multibyte sequences get depicted with the Replacement Character,
and unassigned codepoints are shown as if they were a space. Both have
a width of one.
When running in a non-UTF locale, and when strncasecmp() suffers from
the same defect as strncmp(), make sure not to pass a length with the
high bit set.
Instead of parsing every multibyte character twice, first with
parse_mbchar() and then with mbtowc(), just let mbtowc() do all
the work. This makes searching for a fixed string twice as fast.
This also gets rid of four variables and lots of memory allocations.
(And, more importantly: it stops nano messing up the internal state
of the multibyte-to-wide character conversion, and thus would make
the calls to mbtowc_reset() superfluous.)
(The measurable effect (during long searches, for example) is zero, though.)

Apparently there is /some/ state somewhere after all. Don't have time
now to figure out where exactly.
