r459 breaks; regexp probing, since \< is valid in both POSIX and GNU regexps; they just don't mean the same thing. This means on !GNU, URL matching silently breaks and POSIX word boundries are never tried.

Since the VTE-warning is annoying people, rather than back it out, try to make everyone happy; Linux now only uses GNU, !Linux always probes, and there's now a try_posix_regexp configuration option who's default reflects this.  Hopefully we will Just Work in most environments.
