--- Comment #1 from Warner Losh <[email protected]> ---
This seems like a good observation, though I suspect that we haven't noticed
because the same code will be generated. IIRC (and I may not), the promotion
rules are such that this just works: signed or not 'a' and 'z' don't have any
high bits set so widening to larger types will be the same.

Having said that 'it doesn't matter' kinda, I agree with Paul: this is at least
a logical bug and should be fixed in the manner he describes.
