$ touch /tmp/abbbbb /tmp/abbbbbbbbbbbbbb
Find file or URL:
 / [self-insert-command]
 t [self-insert-command]
 m [self-insert-command]
 p [self-insert-command]
 / [self-insert-command]
 a [self-insert-command]
 b [self-insert-command]
 <tab> [minibuffer-complete]
 <tab> [minibuffer-complete]
 b b [self-insert-command]
 <tab> [minibuffer-complete]
 <tab> [minibuffer-complete]

Now try the same thing in bash outside of emacs.

The user at every moment is aware how many completions there are, and it
only takes a total of two tabs vs. four in emacs.

How about perhaps just adding the space for the user's visual pleasure,
but not using it when processing the command / filename?

Another idea might be not requiring a second TAB before telling the user
[Sole completion] etc. but that would seem too chatty.

Anyway if he really wants a space he could use "\ ".
