Subject: [PATCH] clone: use a more appropriate variable name for the default
 refspec
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

cmd_clone() declares two strbufs 'key' and 'value' on the same line,
suggesting that they are used to contruct a config variable's name and
value.  However, this is not the case: 'key' is used to construct the
names of multiple config variables, while 'value' is never used as a
value for any of those config variables, or for any other config
variable for that matter, but only to contruct the default fetch
refspec.

Let's rename 'value' to 'default_refspec' to make the intent clearer.
