I've started work on this.  I've committed a preliminary change in
commit b851c7543.

As ever, "the devil is in the details."

In my change I used the $category tree instead, because there is a slight
chance it might contain Texinfo commands that need to be converted.
It also needs to be translated with gdt together with a following colon.
This is to change e.g. "Function: " into "Fonction : " in French, with
a space before the colon (although the "Function" part of it may have been
translated earlier, I didn't check).

I doubt that it is possible to hide the colon and space after the category
with CSS.  I found

but this is not enough as we don't know the width of the text.
