Yes, I'd overlooked "require"; but there are instances of "requires to"
which are OK.  The regexp I ended up using was:

    '\b\(require\|allow\|prevent\|permit\|enable\)s\? to\b'

, and some fancy playing around with -A1 and -B1 flags to grep to find
instances (and there were a few) where the verb is at the end of a line
and the "to" at the beginning of the next line (modulo comment markers,
etc.).

Well, I've knocked down quite a few more instances.  I can't guarantee
there're none left, of course, but there aren't many.
