Hi Paul.
r1156750 added a chunk of code in
svn_client__get_repos_mergeinfo_catalog() that appears to be adding a
prefix to a mergeinfo catalog. There is already a function
"svn_mergeinfo__add_prefix_to_catalog()" for doing that; could you use
it? Suggested patch below.
Also r1156750 changed the line "repos_mergeinfo = NULL;" to
"*mergeinfo_cat = NULL;" which I think is wrong because in that case
the following "if (repos_mergeinfo_cat == NULL)" may be testing an
uninitialized value (depending on the implementation of
svn_ra_get_mergeinfo() in the case when it returns an error). See in
the patch below.
