Merge branch 'xl/record-partial-clone-origin'

When creating a partial clone, the object filtering criteria is
recorded for the origin of the clone, but this incorrectly used a
hardcoded name "origin" to name that remote; it has been corrected
to honor the "--origin <name>" option.

* xl/record-partial-clone-origin:
  clone: respect user supplied origin name when setting up partial clone
