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.

This is useful to test local and uncommitted changes in an otherwise-clean source tree. This means that purge will delete: - Unknown files: files marked with "?" by :hg:`status` - Empty directories: in fact Mercurial ignores directories unless they contain files under source control management But it will leave untouched: - Modified and unmodified tracked files - Ignored files (unless --all is specified) - New files added to the repository (with :hg:`add`) If directories are given on the command line, only files in these directories are considered. Be careful with purge, as you could irreversibly delete some files you forgot to add to the repository. If you only want to print the list of files that this program would delete, use the --print option.
