You can now do something like
$ git for-each-ref --format='%C(red)%(refname:short)%C(reset)
%C(blue)%(upstream:diff)%C(reset)' --count 5 --sort='-committerdate'
refs/heads
To get output that's much more customizable 'git branch' output. Future
patches will attempt unify the semantics of 'git branch' and 'git
for-each-ref'.

So my evil plan is to keep extending this format until it's on par
with pretty-formats. Then, we can move towards unifying 'git branch'
and 'git for-each-ref'. This will involve deprecating badly
thought-out options like '-v', and replacing it with the more
powerful '--format'.
I just have one major doubt: in the above output, how do I align all
the upstream branches to the same column? How can I achieve it with
pretty-formats? Something like %*d? But * is already taken to mean
deref in for-each-ref's --format.
By the way, the main motivation for all this comes from the fact that
git for-each-ref is very nicely written :) Look at how it breaks
everything up into atoms and lazily gets the information it needs to
display.
