grep: warn about stray backslashes
This papers over a problem reported by Benno Schulenberg and
Tomasz Dziendzielski <https://bugs.gnu.org/39678> involving
regular expressions like \a that have unspecified behavior.
* src/dfasearch.c (dfawarn): Just output a warning.
Don’t exit, as DFA_CONFUSING_BRACKETS_ERROR now
does that for us, and we need the ability to warn
without exiting to diagnose \a etc.
(GEAcompile): Use new dfa options DFA_CONFUSING_BRACKETS_ERROR and
DFA_STRAY_BACKSLASH_WARN.
