Now you can use "git less HEAD" to view the raw HEAD commit object. It
is really a soft alias (i.e. it can be overridden by any user-specified
alias) to "-p cat-file -p".
This commit refactors the code a bit, to make adding new soft aliases
much easier.
It also adds a few lines in git.txt, so that users actually have a chance
to find out about soft aliases.

How about this?
BTW now it should be easy to add soft aliases for "update", "up",
"checkin" and "ci".

+There are a few hard-coded aliases which can be overridden by explicit
