Now that's a really bad idea in my book... The "ex" in "cex" is
*ex*actly for *ex*pansion, also note the consistency with "mex".

Yup, but I think it is ?par that could use fixing. (The description of
"mex" in there is a bit iffy as well. Why mix character sizes into
something that really deals in interline distances?)

Obvious. In a bunch of other places too, I guess.
