That could be useful - I didn't know about it.

Well, I thing my compctl -Tx 's[~] C[0,[^/]#]' -k users -S/ completion
is doing all I want. I'll try those completion widgets though: they will
probably be useful for alternative user name completion for other
instances.

I don't want a second /. A file URL is of one of two forms:

file:/path
 or
file://host/path

so I only want one / and I deal with s[file://] separately.
Anyway, I have got it working and am not quite sure why it wasn't
working before. Is there a way to have no suffix: -S '' doesn't seem to
work? Anyway, just in case anyone else wants to use it and can be
bothered to adjust it for their local web server name, it is as follows:

compctl -k '(http:// file: ftp:// gopher:// news://)' -S '' \
        -x 's[file://]' -k hostnames -S/ \
        - 's[file:/]' -/g '*.html' -W/ - 's[file:]' -s '`pwd`' -S '/' \
        - 's[http://www.york.ac.uk/~'$USER'/]' -/g '*.html' -W ~/web \
        - 's[http://www.york.ac.uk/~]' -k users -S/ + -u -S/ \
        - 's[http://www.york.ac.uk/]' -g '*.html' -W '/usr/local/web' \
        - 's[http://www]' -k '(.york.ac.uk)' -S/ \
        - 's[http://a]' -k '(tlas.cs.york.ac.uk)' -S/ \
        - 's[http://]' -k '(atlas www)' -S '.' \
        - 's[-]' -k '(anonymous auth base book buried_news cache case
