Subject: Merge branch 'lt/dirwalk' into next
X-Git-Tag: v1.4.1-rc1~94
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=ae12e59a8c895e48d4ef52ac6936674ac7be6370;p=git.git

Merge branch 'lt/dirwalk' into next

* lt/dirwalk:
  builtin-add: warn on unmatched pathspecs
  Do "git add" as a builtin
  Clean up git-ls-file directory walking library interface
  libify git-ls-files directory traversal

Not a conflict, but builtin-add needed to be adjusted to properly
invalidate the cache_tree entry.
