[PATCH 3/5] setup_revisions: remember whether a ref was positive or not

[Sverre Rabbelier <srabbelier@gmail.com>]

From: Johannes Schindelin <Johannes.Schindelin@gmx.de>

This will be required by fast-export, when no commits were
exported, but the refs should be set, of course.

  This is just in preperation of fixing the actual bug.
