[PATCH] diff,difftool: Don't use the {0,2} notation in usage strings

["Štěpán Němec" <stepnem@gmail.com>]

This was the only occurence of that usage, and square brackets are
sufficient and already well-established for that purpose.

Signed-off-by: Štěpán Němec <stepnem@gmail.com>

As per discussion upthread, this notation is not worth keeping; hence
not mentioning it in the v2 of the CodingGuidlines patch and this
removal.
