[RP] Documentation comments

[Jay Belanger]

I just checked out the cvs version of ratpoison, and I just have a
couple comments about the info file.
The command description for `escape' still uses "^b", it should be
"C-b". 
Also, ratpoison and emacs have opposite views of what it means to
split windows horizontally and vertically.  I don't think one meaning
is better than the other, but perhaps the difference should be noted.
