in column lists, enforce the following ordering:

.Bl -column header1 header2 ... <Bl flags>
mixing things up confuses mandoc, and adding flags in can screw up the list.
this hopefully just makes things a bit safer (and more consistent).
(one more bit of work left and all column lists should format how we want)
