Subject: Allow push and fetch urls to be different
X-Git-Tag: v1.6.4-rc0~46^2~5
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=203462347fce0eab563fe77640648a7e8ae64d3b;p=git.git

Allow push and fetch urls to be different

This introduces a config setting remote.$remotename.pushurl which is
used for pushes only. If absent remote.$remotename.url is used for
pushes and fetches as before.
This is useful, for example, in order to do passwordless fetches
(remote update) over the git transport but pushes over ssh.
