:param refspec:
A "refspec" is used by fetch and push to describe the mapping
between remote ref and local ref. They are combined with a colon in
the format <src>:<dst>, preceded by an optional plus sign, +.
For example: git fetch $URL refs/heads/master:refs/heads/origin means
"grab the master branch head from the $URL and store it as my origin
branch head". And git push $URL refs/heads/master:refs/heads/to-upstream
means "publish my master branch head as to-upstream branch at $URL".
See also git-push(1).
Taken from the git manual

underlying git-fetch does) - supplying a list rather than a string
for 'refspec' will make use of this facility.
