Enable ref log creation in git checkout -b.
Switch git checkout -b to use git-update-ref rather than echo and
a shell I/O redirection. This is more in line with typical GIT
commands and allows -b to be logged according to the normal ref
logging rules.
Added -l option to allow users to create the ref log at the same
time as creating a branch.
