When an alias starts with an exclamation mark, the rest is interpreted
as a shell command. However, all arguments passed to git used to be
ignored.
Now you can have an alias like
$ git config alias.e '!echo'
and
$ git e Hello World
does what you expect it to do.

I have this in my $HOME/.gitconfig:
[alias]
debug = !GIT_PAGER= gdb --args git
which allows me to debug, say "git log a..b" by saying "git debug
log a..b".
