The Mercurial fetcher previously used the revision number supplied by Mercurial as its revision count. This is inappropriate, as the revision number is incremented each time a change is added to the local repository, so also changes only reachable from other heads will be counted. For the same reason, it will also depend on whether such changes have been fetched before from the same repository, introducing an impurity. Instead the revisions have to be counted explicitly, similar to the Git fetcher. Change-Id: Idb1e66ae2fb8b05101116c815f453efd6e95b09e
