I will be working on a fix now, but in the meantime please do
not use the "next" branch for real work. Sorry for the
breakage.
Two-way merge by read-tree forgot to invalidate the directories
a new element was added underneath. The fix is simple and will
be in the "next" I'll push out tonight.
OK, done. Will be looking into "binary grep segfault" problem
next.
