Subject: attr: add GIT_ATTR_INDEX "direction"
X-Git-Tag: v1.6.3-rc1~3^2~3
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=4191e80a3e8ee0fa0b8f97f9fba81c3549813fd5;p=git.git

attr: add GIT_ATTR_INDEX "direction"

This instructs attr mechanism, not to look into working .gitattributes
at all. Needed by tools that does not handle working directory, such
as "git archive".
