(re_context_type): Add INSIDE_NOTWORD and NOT_WORD_DELIM, change WORD_DELIM to use WORD_DELIM_CONSTRAINT. * posix/regcomp.c (peek_token): For \B create NOT_WORD_DELIM anchor instead of INSIDE_WORD. (parse_expression): Handle NOT_WORD_DELIM constraint. * posix/bug-regex19.c (tests): Adjust tests that relied on \B being inside word instead of not word delim. * posix/tst-rxspencer.c (mb_frob_pattern): Don't frob escaped characters. * posix/rxspencer/tests: Add some new tests.
