pi,

CC tagging does, indeed, appear to be a small effect.  In some cases it
matters.  For most messages it doesn't matter.

Merging the lexer rules affects the size of the program.  To see how
much difference, build bogofilter (or bogolexer) with the two lexer
versions then use the size command.  The difference will be small.
