Michael,

Indeed it is strange.  Looking through my archive of bogofilter-cvs, I can 
determine the when, but not the why, of the  backslash.  It "crept in" to 
the lexer on May 10.

As you say, there's no apparent reason for being there.  A quick test shows 
that removing it has no affect on the regression tests.  It has been 
permanently excised from bogofilter :-)
