largefiles: teach log to handle patterns

Adding the standin to the patterns list was (possibly) harmless before, but was
wrong, because the pattern list was already updated above that code.  Now that
patterns are handled, it was actually harmful.  For example, in this test:

    $ hg log -G glob:**another*

the adjusted pattern list would have been:

    ['glob:**another*', '.hglf/.', 'glob:.hglf/**another*']

which causes every largefile in the root to be matched.


I'm not sure why 'glob:a*' picks up the rename of a -> b commit in test-log.t,
but a simple 'a' doesn't.  But it doesn't appear to be caused by the largefiles
extension.
