I really like the idea behind this patch, but it has the very small
problem that it colorizes too much.  So in reading this thread, there
are things like “id:’s” and “id:?” that get colored the missing-message
color (a very angry red, by default).  Though this isn’t likely to be a
very frequent problem with email messages that are not on this listserv
:), it would be nice to fix it.  Maybe you could change the regex that
matches id:’s to require a little more structure – an at-sign, perhaps.
Or even requiring more than (say) 5 non-space characters after the
message id would cut down sharply on the false positive rate.
