[PATCH] Make -s flag to show-diff a no-op.

With the recent "no-patch-by-default" change, the -s flag to the
show-diff command (and silent variable in the show-diff.c) became
meaningless.  This deprecates it.

Cogito uses "show-diff -s" for the purpose of "I do not want the patch
text.  I just want to know if something has potentially changed, in
which case I know you will have some output.  I'll run update-cache
--refresh if you say something", so we cannot barf on seeing -s on our
command line yet.
