Merged indexes with subentries

[Akim Demaille]

Hi!

Structured indexes are great, thanks a lot for this!  However they don't work 
well for Bison for three different reasons (two "bugs", and one "missing 
feature"), presented in the attachement. 

> @syncodeindex fn cp
> @syncodeindex vr cp
> @syncodeindex tp cp
> 
> @cindex %define @subentry api.cindex
> @vindex %define @subentry api.vindex
> @findex %define @subentry api.findex
> 
> @deffn {Directive} {%define @subentry api.prefix} @{@var{prefix}@}
> Foo
> @end deffn


gives in PDF:

1. As you can see, the merged indexes do not get subentries, but plain old 
entries.

2. api.cindex is typeset in rm, not in tt as I would expected for the code 
index.

3. I would love to be able to use @subentry in @deffn like structures.  Indeed, 
in Bison that's the way we define our "variable": with its defining %define 
directive.  Unfortunately that's not what happens here, and I can understand if 
you reject this.

Cheers!
