I agree, but I am just too lazy for that. Mine are all one char:

  alias b='/usr/local/bin/git checkout -b'
  alias a='/usr/local/bin/git add
  alias d='/usr/local/bin/git diff HEAD'
  alias c='git commit -m'
  alias i='/usr/local/bin/git pull origin'
  alias o='/usr/local/bin/git branch -avv | grep "\*" | cut -d\ -f 2 | xargs -n 1 /usr/local/bin/git push -u origin'

plus:

  alias g='/usr/local/bin/git log --graph --oneline --decorate 
  alias v='/usr/local/bin/git branch -avv'--all'
  alias h='/usr/local/bin/git log -p'

can be useful.
