shell completion for shell-command input

[Roland Winkler]

Is there a way to have shell completion for the string passed to
shell-command when this command is used interactively? I am so used
to hitting TAB in the minibuffer that I am always frustrated it
doesn't work with shell-command.

I know, inside emacs I can run an interactive shell in a buffer
which will give me shell completion. But I would like to do that
using the minibuffer only. So another possiblity would be an
interactive shell that gets it input in the minibuffer. (However, it
is also an important advantage of shell-command that it uses the
buffer-local value of default-directory for running the shell
command.)
