Correct.

Correct.

Sounds like a good idea.

Wouldn't that leak an error if the error isn't SVN_ERR_BAD_OLD_VALUE?

Also, the current* design requires us to use svn_error_has_cause()
because
the error is wrapped inside an error with a different code. (FWIW,
I think the RA layer shouldn't do that - I think we should change
svn_ra_change_rev_prop() so that the simple test of err->apr_err works.
But that's not urgent, and could even be postponed to 1.8).

Kind regards,

Jon
