Summary: mnewton variable name problem

Initial Comment:
Mnewton uses a subscripted h; this can cause 
trouble. I don't know the cure.

(%i1) load(mnewton)$
(%i2) h[1] : 42$
(%i3) mnewton([x + y - 1, x - y + 23],[x,y],[1,2]);
Unacceptable variable to `solve': 42

The fix is to make h local:

mnewton(FuncList, VarList, GuessList):=
  block([nfunc, Solutions, Increments, solved:false, h, 
         i, j, k, keepfloat:true, ratprint:false], local(h),

This fixes the problem, but then mnewton does not translate.
