This has been years in the making, and we all knew it was bound to happen some day. Switch to the BSDL grep implementation now that it's been a little more thoroughly tested and theoretically supports all of the extensions that gnugrep in base had with our libregex(3). Folks shouldn't really notice much from this update; bsdgrep is slower than gnugrep, but this is currently the price to pay for fewer bugs. Those dissatisfied with the speed of grep and in need of a faster implementation should check out what textproc/ripgrep and textproc/the_silver_searcher can do for them. I have some WIP to make bsdgrep faster, but do not consider it a blocker when compared to the pros of switching now (aforementioned bugs, licensing).
