Our current code has bugs :)

See the HACKING file. The project's knowledge about the use of pools
has developed over time, not all of the existing code follows the best
practice.

You don't appear to have deleted the declaration.

I dislike the way svn_client_revert uses labels irrespective of the
name, it's too easy to introduce a line "SVN_ERR (some_func())" that
isn't "label aware", witness my first comment above. When there is
some essential post-processing that must always be done I prefer to
use a wrapper function, see svn_repos_finish_report in
libsvn_repos/reporter.c.
