apatch/create: don't call cpfile on directories.
Seems to create a valid patch, but I wasn't able to test any of the other apatch/ commands.

This patch should be a good test case: it was created by running the new apatch/create on /rc/bin/apatch.
Will the `apatch' entry in `files', with no corresponding directory entry, break things?


Notes:
good idea, but i'm going to have to sorry this patch because
0-size files need to be legal.  i think you mean -f?
