Well, that is an invalid regex. The + at offset six doesn't follow
anything that can be repeated.

Taking away the surrounding double quotes leaves \\ as \\ so that when
Exim expands it, you end up with \ which makes the regex
-(\w+)(\+.*)?
which is legal. So there's the problem.
With the double quotes, either (a) precede every \ with another \ or (b)
use the \N expansion feature to stop the characters in the regex from
being interpreted by the string expander.
