regex(3)/grot

[Kyle Evans]

Hello!

Over the next week or so, I plan to address inconsistencies in regex(3)
handling of invalid bounds/atom constructs [1] between BREs and EREs, and
found grot [2]. This appears to have once upon a time been the vehicle for
regression testing of regex(3), but seems to have been replaced by the
netbsd test suite (see: [3]).

Does grot still serve a purpose, or can it go away? All of its tests seem
to have been split out into individual tests grouped by functionality in
the netbsd-tests suite [4], which is a model that seems ideal. On top of
that, I'm not smart enough to actually build any of the targets in its
Makefile and I don't feel a compelling urge to make it work on its own.

Thanks,

Kyle Evans
