dfa: fix a subtle constraint encoding bug
* src/dfa.c (SUCCEEDS_IN_CONTEXT, PREV_NEWLINE_DEPENDENT,
PREV_LETTER_DEPENDENT): Rewrite to handle all 3*3=9 possible
combinations of previous and next character contexts.
(MATCHES_NEWLINE_CONTEXT, MATCHES_LETTER_CONTEXT): Remove.
(NO_CONSTRAINT, BEGLINE_CONSTRAINT, ENDLINE_CONSTRAINT,
BEGWORD_CONSTRAINT, ENDWORD_CONSTRAINT, LIMWORD_CONSTRAINT,
NOTLIMWORD_CONSTRAINT): Switch to new encoding.
* NEWS: Document resulting bugfix.
