I see; now it shows up right in the info file:

 - Variable: imenu--index-alist

However, it generates this index entry:

* imenu---index-alist:                   Imenu.

Also, the dvi file shows a long dash as apposed to the desired two

Note that when I do:

@defvar @code{imenu--index-alist}

the double hyphens are handled properly in the sense that it shows up
in info as:

 - Variable: `imenu--index-alist'

and in the info file's index as:

* imenu--index-alist:                    Imenu.

The dvi file shows two hyphens as well.  The only problem, of course,
is that the variable name is surrounded by quotes in the info file and
is shown with a different font in the dvi file.  I think that Texinfo
should be changed so that the @defvr command (I assume that @defvar is
defined in terms of @defvr) handles hyphens like @code.
