Re: merge-tracking -- getting my feet wet

I've extended the notification system to show multiple merges
happening. Something like this:

--- Merging r4 to 'trunk-wc':
U trunk-wc/zcpu.py
--- Merging r6:r7 to 'trunk-wc':
U trunk-wc/zstring.py

There's something odd going on, though. My test script does 3 commits
to the branch (r4, r5, r6). I then port r5 to the trunk and commit,
and finally let the 'magic' merge figure out the remaining ranges by
doing 'svn merge branchURL trunk-wc'.

The merge code should detect two ranges to merge: r4 and r6. But the
svn_merge_range_t's it generates are weird: one is 'r4:r4', and the
other is 'r6:r7'. The thing is, the correct changes seem to be ported

Shouldn't the first range be 'r3:r4'? Why is r4:r4 behaving like r3:r4?
Shouldn't the second range be 'r5:r6'? Why is r6:r7 behaving like r5:r6?
