Let's see how well it fares by cooking it in 'next' ;-)
I think it was <1459349623-16443-1-git-send-email-sze...@ira.uka.de>,
which needs a bit of massaging to apply to the current codebase.

Subject: [PATCH] clone: respect configured fetch respecs during initial fetch
Conceptually 'git clone' should behave as if the following commands
were run:
git init
git config ... # set default configuration and origin remote
git fetch
git checkout # unless '--bare' is given
However, that initial 'git fetch' behaves differently from any
subsequent fetches, because it takes only the default fetch refspec
into account and ignores all other fetch refspecs that might have
been explicitly specified on the command line (e.g. 'git -c
remote.origin.fetch=<refspec> clone' or 'git clone -c ...').
Check whether there are any fetch refspecs configured for the origin
remote and take all of them into account during the initial fetch as
well.
