Subject: add: Support specifying an excludes file with a configuration variable
X-Git-Tag: v1.5.1-rc1~32^2
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=896bdfa2581f96d3df9a312510c39ce7d80790cd;p=git.git

add: Support specifying an excludes file with a configuration variable

This adds the 'core.excludesfile' configuration variable. This variable can
hold a path to a file containing patterns of file names to exclude from
git-add, like $GIT_DIR/info/exclude. Patterns in the excludes file are used
in addition to those in info/exclude.
