Make life faster - one letter aliases

I don't like hit too much my keyboard, so lets reduce it (I'm using fish-shell, but here I give you with POSIX syntax, I think thet fish users are smart enough to rewrite it to their usage):

alias g=git
alias e=$EDITOR
alias b=bundle
alias be=bundle exec
alias brake=bundle exec rake
alias -=cd -

Also some Git aliases should be nice:

b         branch
ca        commit --amend --reuse-message=HEAD
ci        commit
cl        clone
co        checkout
com       checkout master
cp        cherry-pick
d         difftool
f         fetch
lg        log --color --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit
lga       log --color --graph --abbrev-commit --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --all
rollback  reset --hard HEAD@{1}
st        status -sb
ui        !giggle

Now, i.e. to checkout to master you stroke only 6 chars instead of 20. Nice :)
