[StGIT PATCH] Revert 'Disallow non-patch args to "stg show" (gna #8453).'

[Yann Dirson <ydirson@altern.org>]

This patch has a lot of side-effects that will break people's
expectations.  There is much more that just this to do if we want to
sanitize patch/commit/range addressing on the command-line, so that
will wait till after 0.13.
