aborting txn's

Hey,

In trying to get pre-commit hooks working, I have run into an interesting
situation. In hooks.c if the precommit hook fails, then svn_fs_abort_txn
is called on the txn, then the error is returned.

At that point ra_local catches the error and tries to abort the txn again
(which fails). mod_dav_svn on the other hand, never aborts the txn.

My suggestion is that mod_dav_svn should abort the txn, and hooks.c should
leave it alone. Thoughts?
