Summary: hgfred([a,b],[c], 0) -/--> 1

Initial Comment:
I think it would be OK if hgfred([a,b],[c],0)
evaluated to 1. Instead:

(%i1) hgfred([3,9],[7],0);
0^0 has been generated

(%i2) hgfred([3,9],[77],0);
 << Expression too long to display! >>

(%i3) hgfred([a,b],[c],0);
SIMP2F1-WILL-CONTINUE-IN 
(%o3) %f[2,1]([a,b],[c],0)

This is acceptable to me.

Although I can't be sure, but I think the intent of hgfred is to simplify
hypergeometric functions to "simpler" functions.  That evaluation at a
point can happen is an artifact.  But I could be wrong.
