[PATCH 1/2] request-pull: simplify "remote or HEAD" variable in warning messages

[Bagas Sanjaya <bagasdotme@gmail.com>]

In order for waring message "Are you sure you pushed 'remote or HEAD'
there?" to be translatable, replace ${remote:-HEAD} (variable access
with defaults) in the message by referring it as $remote_or_head.
