for-each-ref: introduce %(upstream:track[short])
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: %(refname:short)%(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.
