Handling of patches

testpatch [repository] -r<rev1> -r<rev2>

if they specified repository
then	cd there
fi
bk export -kwr<rev1> /tmp/tp1$$
bk export -kwr<rev2> /tmp/tp2$$
bk resync -r..<rev1> /tmp/tpr$$
cd /tmp
diff -Nru tp1$$ tp2$$ > /tmp/P$$
cd tpr$$
bk -r edit -q
patch -p1 < ../P
# Freak out if there are .rej
cd /tmp
diff -Nru <whatever option it is to ignore SCCS> tpr$$ tp2$$
# freak out if not the same

Construct some little test cases (or find them in our tree) where
the following happens:

a) a file is deleted
	XXX - make sure that if patch deletes a file which has an
	s.file and a p.file associated with it, that patch doesn't
	screw with those.
b) a file is moved someplace else
c) a file is deleted and a new file is created on top
d) a file is deleted and another file is moved on top of it

------

Next step is to pick up /home/bk/lm/src/gnu and figure out how to
extract the creates and deletes from patch.  Run with --verbose
and the information you want is printed, mixed in with a bunch of
other garbage.

First, extract the create/delete events from the patch output.
Second, construct information for renametool so that you can
hand it the lists.  It wants a file like this on stdin

file/which/was/deleted
another/delete
and/one/more

file/which/was/added
another/add
another/file/added
and/one/more
