First of all, I will be willing to contribute the code of
shell-command.el into Emacs core under GPL3.

This code is insufficient, because the output of `message' function
which is called from tab-completion functions will bury the current
completing status in minibuffer.

And more, the customize hook like `shell-command-complete-functions'
will be necessary, in order to enable users to customize tab-completion
functions.
