I think you've got it but let me just redundently spew stuff back at
you to be sure.

It's a category regexp not because of what it can match, but because
it doesn't contain a "/" which is a delimeter of the regexp.

This is a category regexp:


this is an archive regexp:


this is an archive+category regexp set:


and this is an archive+category+branch regexp set:


The point is that '/' is sometimes a delimeter and sometimes not ---
you have to (somewhat, not precisely) parse the regexp to tell whether
a given / is a delimeter.

Oh, and, this is just an error:
