[PATCH v4 00/11] new git check-ignore sub-command

[Adam Spiers <git@adamspiers.org>]

This is the v4 re-roll of the check-ignore series, which is based on
Junio's as/dir-c-cleanup topic branch f6198812 (dir.c: rename
free_excludes() to clear_exclude_list(), 2012-12-27).  As previously
discussed, the earlier parts of the v3 series seem to be complete and
are progressing to 'next'.

Since v3, I addressed the issue of newly public functions with
unacceptably vague or generic names via the following steps:

  - eliminated extraction from add.c to pathspec.c of two functions
    which did not need to be public (validate_pathspec() and
    treat_gitlinks())

  - edited the series history to create separate commits for
    extraction of reusable code from treat_gitlinks() and
    validate_pathspec() into more carefully named public functions

This should make reviewing easier.

I will summarise the changes in the revised patches since v3 in
between the "---" divider and the diffstat of each individual patch.

This series is also available via the check-ignore-v4 tag in:
