Noted. Of course this won't actually make the parsing significantly
easier for script authors, it'll just appear that way at first glance. :)
BTW, in connection with this, I've been wondering which version of what
is actually relevant here. The version of libsvn_client? The version of
the command-line tool? How does this relate to TSVN and/or SharpSVN
and/or SvnKit?
The easy answer is to let the script authors worry about that, but
without at least some kind of guideline, that's a good way of
reproducing the user-agent madness. For example, it would very probably
make sense for TortoiseSVN to report the version of the Subversion
libraries it's built with, but I'm not at all clear how to sanely
formulate such a rule.
