minor feature request: allow 'pass grep' to use grep options and arguments

[Sitaram Chamarty]

Hi

I have ended up with an appreciable amount of metadata along
with my passwords.  As such, I often find myself needing things
like case-insensitive searches, or a couple of lines of context
around the match, etc.

Would this little patch be acceptable?  It removes the
restriction of "exactly one argument" to grep so we can pass in
anything that grep itself will accept.

Thanks!

Subject: [PATCH] pass grep: allow grep options and arguments

Allow grep options and arguments.  Typical uses may be, for instance,
wanting to ignore case ('-i'), print a few lines of context around the
matched line, multiple patterns with '-e', etc.
