Perhaps the caller could catch the error, issue the warning, and skip
processing that svn:externals. The caller already has notification
support.

svn_wc_parse_externals_description3 is also used in upgrade. What do we
do there? I suppose we could do the same, issue a warning and skip
processing the svn:externals.
