Summary: limit(erf(n*x),n,inf) depends on n (x=0)

Initial Comment:
assume(equal(zz,0))$

limit(erf(n*zz),n,inf)  => erf(n*zz)

A limit result should be independent of the dummy
variable! -- in this case result is 0.

For other functions, limit gets this right:

   makelist( limit(f(zz*x),x,inf) ,
               f, [sin,exp,gamma,atan,erf] )

      =>   [0, 1, 1, 0, ERF(x zz)]

Limit/erf works correctly for zz>0 and zz<0.
