largefiles: in overridelog, use non-lf matcher for patch generation (issue4334) This has actually been broken since at least Mercurial 2.8 -- hg log --patch with largefiles only used to work when no largefiles existed. Rev 5809d62e7106 exposed this bug for all cases.

largefiles: drop setting lfstatus in overridelog (issue4334) lfstatus should only be True for operations where we want standins to be printed out. We explicitly do not want that for historical operations like log. Other historical operations like hg diff -r A -r B don't print out standins either. This is required to fix issue4334, but doesn't fix anything by itself. That's why there aren't any tests accompanying this patch.
