hg_delta_editor: do not assume branches are copied from trunk by default Here is what happen in jquery repository: - kelvin-dev branch is created in r1617 with an empty directory for the datePicker plugin - commits are done - datePicker plugin is merged in trunk Before the fix, the converter assumed the initial empty commit had for parent some other commit of trunk, therefore adding all its files, which was wrong. And we ended with 'alignDemo.html' in converted trunk@5946 while it was not in the source revision.
