I was hoping you'd change it to remove the divergence, either by defining

	isAlpha c = isUpper c || isLower c
or
	isUpper c = isAlpha c && not isLower c

The most sensible meaning for isAlpha seems to be the Unicode Letter
category, which falls between glibc's implementation of these two,
though the second is closer.  (isAlphaNum is not affected)
