   In nornal menus, things look like:

   whereas in indices, the description is missing and things look like:

           * menu:                      entry.

   note the clever use of he fact that whitespaces between `menu:'
   and `entry.' is ignored.

But the question is: how does that difference have anything to do with
whether or not colons should be hidden?

On another note, the whitespace is ignored by makeinfo and the
stand-alone Info reader, but not by Emacs.  In Emacs

* menu: entry                description. 

will visit entry, but

* menu:entry.                description.

will yield an error.  It does not matter if one replaces "menu" by
some less ambiguous name.  The stand-alone Info visits entry.

Emacs insists on the space after the colon, because it wants to
support colons in the middle of menu subtopic names.

Sincerely,
