The test really states what this is about. Inspired by bug report #504
(which I suspect refers to an already-fixed bug), I wrote a test script
that darcs fails involving adding and removing a binary file. I then have
two patches that fix the bug. One works by avoiding generating the null
binary patches in the first place, and the other by allowing coalesce to
eliminate them once they're generated. I suspect both are good changes to
include, and I may move these bugfixes into darcs-stable soon. They aren't
very serious bugs, but they're very simple bugfixes.
David.

David Roundy <[EMAIL PROTECTED]>**20050903132055
The trouble was that the NoPristine version of createPristineDirectoryTree
would fail if the directory already exists, which isn't the intended
behavior. I also took this opportunity to remove the "stubbornly" function
and replace some stubborn directory creation with
createDirectoryIfMissing.
