I'm not opposed to the patch, but you could just cd $PWD-branchname in
this case. It's also easy to get the desired functionality with a
wrapper function (admittedly slightly less easy if you also want to
handle edge cases like cd -L '' foo but you probably don't):
cd() {
  if [[ $# == 2 ]] && [[ $1 = "" ]]; then
    builtin cd $PWD$2
  else
    builtin cd "$@"
  fi
}
