default aliases (ci, di, st, co)

Hi,

coming to git from mercurial and svn, here is the alias part of my .gitconfig:

[alias]
    ci = commit
    di = diff --color-words
    st = status
    co = checkout


And all is fine until I share commands to checkout my branch (for
example) with other people, then basically I have to write those
commands in full (e.g. commit, checkout, ...), since I cannot assume
they have their .gitconfig setup the same way I do. Especially for
people who are new to git.

What is the view on this in the git community? Do most of you write

git checkout -b branch ...

(possibly with TAB completion) or do most of you write

git co -b branch ...

(like I do all the time, except when sharing my commands with other people)?

Could in principle those aliases be even made default by git? Or is
this not a good idea.
