Empty tree gives a parse error

[taralx]

Tree parsing is defined as all_consuming(many1(parse_entry)), which rejects the (valid) empty tree. I'm pretty sure that should be many0.

Thanks for pointing this out - I couldn't agree more! These trees seem to be a true rarity in real world repositories, but it's not a reason to fail either :).

If you feel like becoming a contributor, a PR for this would be very welcome. It should be trivial to drop down an empty file for a test and see it succeed with the fix applied.
