[PATCH v2 0/4] [GSOC][RFC] ref-filter: add %(rest) atom

In order to let git cat-file --batch reuse ref-filter logic, the atom
%(rest) and %(raw) are added to ref-filter.

Change from last version: Use printf "xxx" instead of printf "%b" "xxx" in
test, ensure that strings containing NUL will not be truncated, to avoid the
breakage of the test.

ZheNing Hu (4):
  [GSOC] ref-filter: add obj-type check in grab contents
  [GSOC] ref-filter: add %(raw) atom
  [GSOC] ref-filter: use non-const ref_format in *_atom_parser()
  [GSOC] ref-filter: add %(rest) atom
