regexp filter

[David Magda]

Hello,

Trying to setup use a filter (through 'L') to get rid of common span
in Usenet. Specifically, I'm trying to get rid of spam with subject
line like the following:

    Britney Spears and justin timberlake  8272

So I do a key sequence of L-> s -> r -> t. When asked for the string
I tried ".*  [:digit:]{4}" as well as ".*  [0-9]{4}" (throwing in a $
at the end would also make the regexp more precise). I also tried
escaping the spaces ('\ ').

The above spam (and many others like it) have a predictable sequence
of '<space><space><number><number><number><number>'.

Any ideas?
