[PATCH 0/5] fast-export: prepare for remote helpers awesomeness

During a funathon with a lot of sheep baaah-ing in the background, we discovered this ancient fast-export bug while working on finishing git-remote-hg. So, here it goes.

Johannes Schindelin (4):
  fast-export: do not refer to non-existing marks
  setup_revisions: remember whether a ref was positive or not
  fast-export: do not export negative refs
  setup_revisions: remember whether a ref was positive or not

Sverre Rabbelier (1):
  t9350: point out that refs are not updated correctly
