Rework and fix HGSourceCodeManager >> #revisionLogOf:...directory:module:` This commit changes the logic in two ways: 1. #newestRevision is now the newest revision in the branch that *contains* given file (not necesarily modidfes it). If there are multiple heads in that branch, pretty much random one is returned. This changes old behavior and therefore this commit updates tests. 2. If a specific single revision is requested, i.e., both from and to revisions are the same, revision log with that single revision is returned no matter whether it modifies the file or even contains that file at all. This is essentially a workaround to fix issue #305. Moreover, this commit simplifies the code a lot by delegating all the changeset searching and filtering to mercurial using revset expressions.
