Enhance 'git for-each-ref' with color formatting options. You can now
use the following format in for-each-ref:
%C(green)%(refname:short)%C(reset)

'git branch' shows which branch you are currently on with an '*', but
'git for-each-ref' misses this feature. So, extend its format with
%(HEAD) for the same effect.
Now you can use the following format in for-each-ref:
%C(red)%(HEAD)%C(reset) %(refname:short)
to display a red asterisk next to the current ref.

Introduce %(upstream:track) to display "[ahead M, behind N]" and
%(upstream:trackshort) to display "=", ">", "<", or "<>"
appropriately (inspired by contrib/completion/git-prompt.sh).
Now you can use the following format in for-each-ref:
%C(green)%(refname:short)%C(reset)%(upstream:trackshort)
to display refs with terse tracking information.
Note that :track and :trackshort only work with "upstream", and error
out when used with anything else.
