we see a shell break character; turn it on or keep it on when
not a break character. Keep track of word length (reset to 0
when we turn on LEX_INWORD when it was off).
- don't use COMMENT_BEGIN in parse_comsub any more; test
whether or not LEX_INWORD is set and lex_wlen == 0 in addition
to tests for LEX_RESWDOK and lex_rwlen. Comments are valid

parse.y
- in parse_comsub, when looking for a reserved word (LEX_RESWDOK
non-zero), and in a case statement, we can see either an esac
or a pattern list. We handle an esac separately. We should
turn off LEX_RESWDOK if we see anything but a newline, since
we'll be reading a pattern list. Other part of fix for bug
reported by Mike Frysinger <vapier@gentoo.org> (rest of fix
