In retrospect, because --pickaxe was designed primarily for Porcelain use,
it was a mistake for it to have taken a short-and-sweet -S synonym.

Hmm. I actually like the pickaxe behavior and find it useful for
searching. IOW, I consider it a porcelain feature, just perhaps not the
one that some people are expecting.

Look for differences that change the number of occurrences of <string>?

Yes, that is technically correct. I was trying to find a wording that
was a little less "this is literally what it does" and more "this is
what you might find it useful for".

Is there any way to have an option to also match any line containing
the string?

Patches welcome. I've already outlined what you need to do.

I think it can be called -G (short for --grep-diff), if --search cannot be
used because "-s" is unavailable.
