I can't think of an easy way to do this. Herb wasn't suggesting such
a test, he was suggesting unconditionally replacing all the headers
(however many there are, as long as there is at least one) with a
single good one.

I'm not sure what you're asking. In general, exim doesn't use
headers for anything. If you mean what does $header_foo: contain
when there is more than one foo: header, TFM says:
If there is more than one header with the same name, they are all
concatenated to form the substitution string, up to a maximum length of
64K. A newline character is inserted between each line.
