You have to add the `-o nospace' option after `complete' instead of
`compgen'.  See diff.

You can take a look at `scp' completion in file `contrib/ssh' which
already solves processing `:'.  Note the: cur=`_get_cword ":"` (?)
I found it difficult though: I tried copying things to wget
but couldn't get it work.  Maybe you can give it a try.

Or use bash parameter expansion (see also diff):

COMPREPLY=( $( compgen -W "http{,s}://{,www} ftp://" -- $cur ) )
