Re: [TS 27522]--Re:Re: PageWidth option is not measured in characters

I, too, think it is in printers points for non-keyboard character displays.

However, the docs don't come out and say it ... which can be a little
confusing when other typesetting commands, such as the GridBox option
for column spacing actually do measure in "characters" (AFAIK)

Maybe this is could be a candidate for a quick documentation patch?

Peace,
