Agreed.

BTW File will receive a couple more ranges: byDchar which spans the file 
one dchar at a time, byWchar which is sometimes necessary due to the 
awkward fwide API (see 
http://www.opengroup.org/onlinepubs/007908775/xsh/fwide.html), and 
byChar for getting one narrow character at a time. (Or should that be 
byUbyte or something?)

As I mentioned in another email, these are implementable with good 
efficiency using nonstandard APIs. Otherwise each iteration will cost 
one call to fgetc and one call to fungetc.
