[exim] filter out re[] mails

Hi,

I have the following in my filter:

# this filters blocks mail with the subject 're[nn]'

if      $h_subject: matches re\\[\\d+\\]\$ or
        $h_subject: matches re:\\[\\d+\\]\$ or
        $h_subject: matches re:\s\\[\\d+\\]\$ or
        $h_subject: matches re\s\\[\\d+\\]:\$ or
        $h_subject: matches re\s\[\d+\]:\$ or
        $h_subject: matches re\s\[\d+\]\$ or
        $h_subject: matches re\\[\\d+\\]:\$ then
        freeze
endif

I am trapping most of the mails but ones with a white space between
the re and the first [ are getting through. I thought the /s would
match a single white space, have I got it wrong?

I have slightly over-cooked this filter to try and get the variation
of mail, and there are a few too many escapes in the above. I have
tried escaping the \s in the past but that didn't seem to work. I am
sure someone could help condense this down to two lines. Any ideas?

Cheers.
Dp.
