SpamAssassin should be just about here for most REs -- at least the ones
that operate in "body" tests, due to splitting lines at an arbitrary limit
of 2048 chars (that's MAX_BODY_LINE_LENGTH).

If this issue appears in header regexps, or "rawbody" or "full" tests
though, we probably need to do something similar there too...
