> I need to define a pattern which is invalid as form field input. i.e. I have
> a user feed back from that receives a lot of spam but the names are normally
> something like "xtrqkjitvxqoh". Instead of having a capture I want to set
> names with 5 successive consonants as invalid.
> This patch does the trick...
