Wait, just so I understand: your solution would imply that
tex.dimen["textwidth"] holds a number, not a dimension, right? (Because
you simply concatenate it with a dimension unit). Which makes sense when
I think of it because lua has no concept of dimensions, only of strings,
functions, tables, numbers... Whereas the Wolfgang implies that the
result is already in sp. So who's right?
