bug#12725: dired-do-shell-command should allow . and ..

[Stefan Monnier]

> In dired buffer, hitting `!' on current directory (`.') or parent
> directory (`..') results in the error
>    dired-get-filename: Cannot operate on `.' or `..'
> There is no reason this should not be allowed. Please allow running
> commands on these two.

I've installed the patch below which seems to fix your problem,
thank you for bringing it up here,
