Re: Colon in index items

[Karl Berry]

    Two colons in a row signal the end of the menu item and the beginning of 
    text that the reader ignores.  If you can have two colons as part of the 
    entry itself, how do you tell which one is the ``real'' end?

Ah. I think I see what's going on.

Ordinary menus in a manual have entries that generally look like
* Foo::   Some description.
where Foo is both the menu item label and the node name.
Indeed, clearly these cannot be disambiguated without quoting the Foo.

However, index entries use the otherwise-uncommon form of menu item
* Label: Nodename.
where the label is given separately from the node.
I think these *can* be disambiguated by the regexp I gave before.

Whether it's worth it is another matter, since it doesn't solve the
problem in general.

Thanks,
