grep: Listing files without lines matching a pattern

In my version of GNU grep (see below) using both *-l* and *-v* (in that
order) leads to *-v* being silently ignored.

My intent by using *-l* and *-v* was to achieve the effect of *-L*,
listing files without lines matching a pattern.  Seeing the option *-v*
being silently ignored in this context is a surprising effect, which
should be documented and maybe could lead *grep* to fail with a “Usage”
error.

Best regards,
Michael Grünewald
