doc: man: fix -L description and improve -l's

* doc/grep.texi (-L): Remove erroneous sentence about stopping early.
With -L, grep cannot stop scanning early.
(-l): Tweak existing wording.
* doc/grep.in.1: Remove the -L sentence here, too.
(-l): Copy the sentence from grep.texi, to clarify: it's only per-file
scanning that stops upon match.  Reported by Robert Bruntz
