I can see the argument that ch = -1 is the same as ch = 65535 (since ch 
is unsigned)

ch++ is the same as ch = ch + 1 and ch being unsigned in this case would 
promote to int, and int 65535+1 overflows.

The weakness is that I am not sure that ++ does the usual arithmetic 
conversions for the increment operation (it would for the value returned 
for the expression).
