OK. This patch adds the nth root command, as well as a short section on math
text mode. Both are really short. For the math text mode thing, I basically
just used what you wrote at me, JMarc. Take a look at it and fix what you
want.

+Math Text Mode
+\layout Standard
+
+Tyepfaces are useful for entering variable names in some given typeface,
+ but certainly not for anything else, and in particular not text.
+ For typing longer pieces of text, use math text mode, which is obtained
+ by typing
+\family sans
+M-m m
+\family default
