Can anyone shed light on the meaning and purpose of "set_target_revision()" in
the delta editor?
I'm just trying to understand this for tree-conflicts work, as it might be
relevant for helping to detect whether the working copy being edited matches
the merge-left source.
[[[

svn_revnum_t target_revision,
apr_pool_t *pool);

Thanks for any help.
