[PATCH v3 00/19] new git check-ignore sub-command

[Adam Spiers <git@adamspiers.org>]

This v3 re-roll of my check-ignore series is a reasonably substantial
revamp over v2, and applies on top of Junio's current
nd/attr-match-optim-more branch (82dce998c202).

All feedback and patches from the v2 series has been incorporated, and
several other improvements too, including:

  - composite exclude_lists have been split up into
    exclude_list_groups each containing one exclude_list per source

  - smaller commits for easier review

  - minor memory leaks have been fixed and verified via valgrind

  - t0007-ignores.sh has been renumbered to t0008-ignores.sh to avoid
    a conflict with t0007-git-var.sh

  - improvements to documentation and comments

For reference, the v2 series was announced here:

    http://thread.gmane.org/gmane.comp.version-control.git/204661/focus=206074

All tests pass except for t91*, since there seems to be some
pre-existing breakage in 82dce998c202 relating to git-svn.
