Indeed - this still leaves the question open as to whether to have a
mechanism that toggles the behaviour (and defaults to the current
behaviour) or whether to have another variable ${message_body_nl} .
The former saves unnecessary memory allocations and data copies, while
the latter means that you can easily do both kinds of search in the
same filter.

Spot on! As another reply mentions, it's impossible to do this correctly
(ie without risk of false positives) if you can't distinguish between
space and new-line.
