[darcs-devel] [issue2493] Darcs.Patch.Apply.effectOnFilePaths broken/incomplete?

[Ben Franksen]

New submission from Ben Franksen <benjamin.franksen at helmholtz-berlin.de>:

Suppose you have a repo with one file, say "a", in the recorded state
and your unrecorded changes include a file move ./a -> ./b
Then

 effectOnFilePaths (invert unrecorded) ["a"] == ["a"]

I would have expected to get ["b"]; more generally I would expect

   effectOnFilePaths (invert x) . effectOnFilePaths x
==
   id
==
   effectOnFilePaths x . effectOnFilePaths (invert x)

This looks like a bug to me.
