Subject: [PATCH 1/2] Add a new option 'core.askpass'.

From: Knut Franke <[email-masked]>
Date: Fri, 27 Aug 2010 12:51:15 +0200

From: Anselm Kruis <[email-masked]>

Setting this option has the same effect as setting the environment variable
'GIT_ASKPASS'.

This is useful if you have a wrapper script around git-clone doing some site-
specific customizations, but want users to be able to use plain git commands 
for other operations.
