revert: evaluate filesets against working directory (issue4497)

As the failing revert tests in test-fileset-generated.t show,

Revert currently creates one matcher for matching files in the working
copy and another matcher for matching files in the target
revision. The two matchers are created with different contexts, which
means filesets are evaluated differently. Then the union of the sets
of files matching the matchers in the two contexts are reverted. It
doesn't seem to make sense to use two different matchers; only the
context they're applied to should be different.

It seems very likely that the user wants the filesets to be evaluated
against the working directory, which the tests
test-fileset-generated.t also assume, so let's make it so.

I willingly admit that the largefiles code was modified by trial and
error (according to tests).
