I started out updating Guidebook.mn to use \(oq and \(cq for single
quotes but ended up including some new text. I've separated that
part out (there are a few instances of altered quoting in the midst
of it--the separation wasn't 100%) to commit separately.
Add verbiage to "choosing race" and several commands: f, s, S, t,
w, and ^X.
Change `E-' and `w-' to use minus sign instead of hyphen. The TeX
edition uses \tt font for those which has the same effect of making
those dashes be more prominent.
Fix typo/thinko in `IX': Guidebook.mn and Guidebook.txt said that
displayed inventory items whose bless/curse state is "known".
Guidebook.tex had it right, "unknown".
