Subject: pull: pass upload_pack only when it was given
X-Git-Tag: v2.5.1~5^2

pull: pass upload_pack only when it was given

The upload_pack shell variable is initialized to an empty string, so
conditional expansion with ${upload_pack+"$upload_pack"} would not
work very well.  You need a colon there.
