[PATCH 0/3] refspec: refactor & fix free() behavior

Since Martin & Brandon both liked this direction I've fixed it up.

Martin: I didn't want to be the author of the actual fix for the bug
you found, so I rewrote your commit in 3/3. The diff is different, and
I slightly modified the 3rd paragraph of the commit message & added my
sign-off, but otherwise it's the same.

Martin Ågren (1):
  refspec: initalize `refspec_item` in `valid_fetch_refspec()`

Ævar Arnfjörð Bjarmason (2):
  refspec: s/refspec_item_init/&_or_die/g
  refspec: add back a refspec_item_init() function
