Mark and I talked about this recently and came to the conclusion that
making the proposed behavior the *default* for --record-only is
probably the best approach. Merge tracking is complicated enough
without introducing new options and, as described above, the
performance price for this change should be reasonable.
The attached patch makes --record-only apply only svn:mergeinfo diffs
by default. It shows notifications for any path updated (unlike
--record-only's current behavior which never shows any notifications).
It also adds a new merge test to demonstrate the new functionality.
Any thoughts, questions, and/or objections to this change let me know.
Barring any objections I'll be committing this sometime this week.
Let --record-only merges apply svn:mergeinfo diffs.
See http://svn.haxx.se/dev/archive-2009-09/0520.shtml for discussion.
(merge_props_changed): Only allow svn:mergeinfo prop changes to be changed.
Exit early if this is a --record-only merge.
(notification_receiver): If performing a --record-only merge, limit
notifications to mergeinfo changes.
(do_directory_merge): Actually drive the editor for --record-only merges.
(record_only_merge): New test.
(test_list): Add record_only_merge.
