That part's already set up -- the property is get_revision.  The
problem is that, on the slave side, buildbot runs 'svnversion' to
determine the revision it got.  Using an export, of course, svnversion
can't determine a revision, and gives nothing.

I think that the fix would be to either parse the results of 'svn
export', which ends with
Exported revision \d+
or to run an 'svn info' against the repository before making the
export (which introduces a small race condition)

I would certainly be in favor of a patch to implement either of those.
