In general, this rather seems like an option not to use. But let's see if the idea can be salvaged. When the first patch in the input creates a file in a sub-directory (or removes a file and is applied in reverse), the guess will fail if that sub-directory doesn't exist: --- /dev/null +++ a/dir/foo @@ -0,0 +1 @@ +foo I guess it would make sense for patch to refuse guessing in that case? What should happen when patch finds multiple of the names in the patch (pch_name)? Should the minimum strip level be used? How does this interact with -R guessing as with the following patch (apply in an empty directory with -p0)? --- /dev/null +++ bar @@ -1 +0,0 @@ -bar The "/dev/null" patch doesn't make sense to me. If we want this kind of guessing, we should document how it works and when it doesn't. This needs to become a new long option; we can't cram it into -p. Thanks, Andreas
