Yeah, the author/committer search piggy-backs the more generic "grep
in the log" machinery, but it is quite hidden and the document
failed to tell the end users that is what is going on.  Mentioning
that invert (or any tweak that works on the grep machinery) affects
author/committer search is a good idea.

Does "-i/--regexp-ignore-case" also need the same treatment?
