lfs: always exclude '.hg*' text files

I can't think of any problematic scenarios (though things might get interesting

Test rebase with obsolete

Enable obsolete

Start rebase from a commit that is obsolete but not hidden only because it's
a working copy parent. We should be moved back to the starting commit as usual
even though it is hidden (until we're moved there).
