dired-do-shell-command needs minibuffer completion

[jidanni]

! runs the command dired-do-shell-command

Well, it could certainly use the same completion list for command
names as comint-dynamic-complete. Currently TAB at its prompt just
does self-insert-command.

dired-read-shell-command and dired-smart-shell-command in dired-x.el
need some love too.

What you want is to be able to complete against the history of shell commands
used in Dired, `dired-shell-command-history': to reuse a previous command,
possibly editing it first. Right?

That's easy to do, and it need not be limited to shell commands or Dired.

With Icicles, you can, during any minibuffer input, use `M-o' to complete
against the current history. In this case, the history is
`dired-shell-command-history', so you complete against shell commands previously
used for `!' in Dired. This comes for free; it's not something designed
specifically for shell invocation in Dired.

If you want to do the same thing without Icicles, it's not hard. See command
`icicle-insert-history-element', which is bound to `M-o' in all minibuffer
keymaps. It uses a recursive minibuffer, passing `minibuffer-history-variable'
to `completing-read' as the completion alist.

I proposed this feature for Emacs, but who knows what will come of that. See my
March 15 and 16 mails to the thread "Usability suggestion : completion for M-:"
on emacs-devel@gnu.org.

No, not that fancy: all I know is that the first word entered when
using ! (dired-do-shell-command) must be a file on $PATH, so hitting
TAB should expand on all the executable filenames in /usr/bin/ etc.
for that first word.
