The shortest extended commands were being formatted differently in
Guidebook.txt than longer ones, looking a little odd. Force them to seem
longer so that they all end up with similar formatting.
Untested; based on how short option names are handled. And I have no
idea whether the TeX version ought to have something similar done; I lack
the means to view it. (In theory I could format it into Postscript,
transfer the result to a PC [a different one than what I'm using as a
terminal], convert it into PDF there, then use Acrobat to look at it. In
practice, that's more effort than I care to expend for something so minor.)
