I saw the same history, and I do not really know the answer. Clearly
the current output is wrong (in my opinion). /branches/c only has
three points of history.

r5 branch was created from /trunk
r15 branch was caught up with changes on /trunk
r16 a change was made

I would assume r5 and the information it brings with it should be
pretty easy to exclude.

r15 is the real question. I guess you would have to see that r15 was
a merge that came from the same location you are checking the logs
for, and know to exclude it.

Put another way. If I were looking at the history of /branches/c I
would expect it to show r15 and what that revision merged into the
branch. But when looking at the history of /trunk, it seems wrong to
show the revisions where something happened on the branch that came
from trunk.
