[PATCH v5 09/10] diff: --pickaxe-{all,regex} help: Add --patch-{grep,modifies}

[Illia Bobyr <illia.bobyr@gmail.com>]

For less experienced users --patch-{grep,modifies} should be easier to
understand than just -S or -G.  By mentioning the long argument names in
the help messages we save those users from having to search the list of
options for an explanation of what -S or -G stand for.
