Subject: [PATCH] Restrict tar transform to regular files Without this
 restriction, symlinks are rewritten and corrupted.

Example without the restriction:

Input tree (valid):
package-githash/file1
package-githash/link -> ./file1

Output tree (broken):
package-githash/file1
package-githash/link -> package-githash/file1
