Subject: Add core.pager config variable.
X-Git-Tag: v1.5.3-rc1~93
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=54adf3706c5c799584c1bcdcac96fb3285b97de4;p=git.git

Add core.pager config variable.

This adds a configuration variable that performs the same function as,
but is overridden by, GIT_PAGER.
