Thanks for the report. That has highlighted the fact that the sentence
in question doesn't even make sense for -L, so I've deleted it. Note
that for the -l option, this was documented properly in grep.texi (the
primary documentation -- you can read via "info grep"), but I've
tweaked the wording there slightly and propagated that wording to the
man page.

I'll push the attached later today.
