The MATCH would always start with whitespace, because the ' *' will

Greedy _leftwards_ ?!?

Yes, see the procmail man pages.

All the manpage says it this:

Some non-optimal and non-obvious regexps set MATCH to an incorrect
value.  The regexp can be made to  work by removing one or more
unneeded '*', '+', or '?' operator on the left-hand side of the \/

I don't see how my '*' is "unneeded", as removing it will change the
set of strings
covered (it won't match when there's no leading whitespace).
