This is almost certainly issue #1421 (whose cause is known now, I'm
writing a regression test currently & then will fix).

The issue isn't whether the branch as a whole was copied from 1556,
but whether file2 was correctly spliced in from 1544. However, note
that a parent (or grandparent, etc) of file2 could have been copied
from an earlier revision. Did you check for that?

I just put in print statements :-). You might want to just wait until
current issues are fixed and just try again, though, especially #1421.
