revset: evaluate filesets against each revision for 'file()' (issue5778)
After f2aeff8a87b6, the fileset was evaluated to a set of files against the
working directory, and then those files were applied against each revision. The
result was nonsense. For example, `hg log -r 'file("set:exec()")'` on the
Mercurial repo listed revision 0 because it has the `hg` script, which is
currently +x. But that bit wasn't applied until revision 280 (which
'contains()' properly indicates).
This technique was borrowed from checkstatus(), which services adds(),
modifies(), and removes(), so it seems safe enough. The 'r:' case is explicitly
assigned to wdirrev, freeing up rev=None to mean "re-evaluate at each revision".
The distinction is important to avoid behavior changes with `hg log set:...`
(test-largefiles-misc.t and test-fileset-generated.t drop current log output
without this). I'm not sure what the right behavior for that is (1fd352aa08fc
explicitly enabled this behavior for graphlog), but the day before the release
isn't the time to experiment.
