subrepo: compare svn subrepo state to last committed revision
A subversion project revisions are a subset of the repository revisions, you
can ask subversion to update a working directory from one revision to another
without changing anything. Unfortunately, Mercurial will think the
subrepository has changed and will commit it again. To avoid useless commits,
we compare the subrepository state to its actual "parent" revision. To ensure
ascending compatibility with existing subrepositories which might reference
fake revisions, we also keep comparing with the subrepo working directory
revision.
NOTE: not sure if this should go in stable or not.

12389 | 17 .. note:: |
18 using rollback or extensions that destroy/modify history (mq, | |
19 rebase, etc.) can cause considerable confusion with shared | |
20 clones. In particular, if two shared clones are both updated to | |
21 the same changeset, and one of them destroys that changeset | |
22 with rollback, the other clone will suddenly stop working: all | |
23 operations will fail with "abort: working directory has unknown | |
24 parent". The only known workaround is to use debugsetparents on | |
25 the broken clone to reset it to a changeset that still exists | |
26 (e.g. tip). | |
