And it really annoys me too because usually, instead of an immediate
"command not found", you've got a reply seconds later if on a not so
fast computer. When working on Ubuntu, after a typo or missing command
I have the time to realize that something strange is happening, to
read again what I typed and to hit ^C before any message is displayed.
