Spelling patch needed for polchebyshev in help

[Donald Parsons <dparsons@brightdsl.net>]

Hello PARI-dev,

I just noticed a mis-matched spelling for ?polchebyshev
in the help:

(20:18) gp > ?polchebyshev
polchebishev(n,{flag=1},{v=x}): Chebychev polynomial of the first
   (flag = 1) or second (flag = 2) kind, of degree n, in variable v.

(20:18) gp > ?polchebishev
polchebishev: unknown identifier

(20:20) gp > polchebishev(2,flag=2,v)
  ***   unknown function or error in formal parameters:
           polchebishev(2,flag=
           ^--------------------

(20:28) gp > polchebyshev(2,flag=2,v)
%3 = 4*v^2 - 1

There are many more hits for y spelling.  So I'm not doing a
simple patch.
