Nice. Thanks for testing. That's good to know.
That said, I think an improvement for svnlook is still sorely needed.
A lot of installations out there don't have bindings installed, plus a
lot of existing (sometimes publicly available) hooks are written for
svnlook (to be as generically useful as possible). Like this very nice
configurable pre-commit hook:
Anyway, I don't have the cycles to work on this myself, but I just
wanted to mention this as an important aspect if more and more tools
are going to validate properties in pre-commit hooks (like for
enforcing merge policies).
