Nitpicking: Because of the odd way Procmail's variant of \< works
[it always matches one non-word character, not just a "zero-width
assertion" like most regex implementations that have this construct],
this will fail when there is no whitespace after the colon. This is
rather pathological but still perfectly compliant with RFC822. For
this reason, you should use (.*\<)? instead of just .*\< after the
colon that terminates a header field name.

(When, not if, Microsoft launches another mail handling program which
doesn't comply to RFCs, not to mention even Microsoft's own specs,
you'll owe me a virtual beer if it doesn't add whitespace after header
colons :-/
