I meant reading the patch file and doing the edit yourself.  Probably not
what you want to do...

For this I'd use darcs diff -u followed by "patch -p0 < patchfile".

The problem is that darcs doesn't have any capability for doing inexact
patching, and in the situations you're describing, I don't think you're
wanting to apply the patch to a file which is identical to the version for
which the patch was created.
