"svnlook pl --revprop" does not work on transactions?

Hi all,

It seems that I encountered a bug in 'svnlook pl --revprop': it fails with
the following message:

$ svnlook pl --revprop -t 10547-86b /svn/test-svn
svnlook: Invalid revision number '-1'

Observed with Subversion 1.6.6. Looks like offending code is this block in
do_plist():

==============================
  if (path != NULL)
    ...
  else
    {
      SVN_ERR(svn_fs_revision_proplist(&props, c->fs, c->rev_id, pool));
      revprop = TRUE;
    }
==============================

Note that it always uses svn_fs_revision_proplist(), even when '-t TXN' is
passed. In this case, c->rev_id == SVN_INVALID_REVNUM (-1), and
svn_fs_revision_proplist() rightfully fails.

Shouldn't it be using svn_fs_txn_proplist() instead, just as
get_property() chooses between svn_fs_txn_prop() and
svn_fs_revision_prop()?

This conditional is still in /trunk, so most likely, bug is also
reproducible with top-of-trunk Subversion.

Regards,
Alexey.
