#6 Remove spaces from Category HTML target

[John Busco]

If the <C>category is multiple words separated by
spaces, then the resulting HTML will have a space in
the link target. This causes an HTML checker like Tidy
to complain:

line 39 column 5 - Warning: <a> escaping malformed URI
reference

Also, I've found these URLs troublesome to cut and
paste. It would be better if you compress the spaces
out of the Category name when generating the HTML link
target.
