 Replying to [comment:7 mojca@…]:
 > This is somewhat similar to René's case with the need to rename file
 after it has been fetched.

 Yes, and my case used to be even more similar. Before I discovered the
 github mirror where one can fetch a tarball, I actually had to do a manual
 git clone in the post-fetch. And to avoid the associated overhead I
 archived that check-out so that a rebuild would be able to unpack a
 tarball in the post-extract phase.
