[PATCH v4 0/8] port the filtering part of branch.c to use ref-filter APIs

[Karthik Nayak <karthik.188@gmail.com>]

This makes branch.c use the ref-filter APIs for filtering of
refs for 'git branch -l'. This is part of the series of unification
of code of 'git branch -l, git tag -l and git for-each-ref'.

The previous version can be found here:
http://thread.gmane.org/gmane.comp.version-control.git/276377

The changes in this version are:
[7/8]: Change the tests check for stdout and stderr. (check interdiff)

Karthik Nayak (8):
  branch: refactor width computation
  branch: bump get_head_description() to the top
  branch: roll show_detached HEAD into regular ref_list
  branch: move 'current' check down to the presentation layer
  branch: drop non-commit error reporting
  branch.c: use 'ref-filter' data structures
  branch.c: use 'ref-filter' APIs
  branch: add '--points-at' option
