2020-06-08Remove reference to FreeBSD-specific libedit hackJune McEnroe
Newer versions of libedit have sane tab-complete now without FreeBSD's hacks, and in fact the hack is gone in FreeBSD-CURRENT. I'm still a little confused why binding this weird function is necessary at all, but at least it exists everywhere, I guess.
