Subject: for-each-ref: Do not lookup objects when they will not be used

for-each-ref: Do not lookup objects when they will not be used

This makes commands such as `git for-each-ref --format='%(refname)'`,
which are used heavily by the bash_completion code, run about 6 times
faster on an uncached repository (3 s intead of 18 s on my linux-2.6
repository with several remotes).
