If there's no security implication (it's hard for me to imagine, but
I'm not very imaginative) I think ignoring whitespace in the beginning
and middle of the string makes a lot of sense.  I could come up with a
couple of more fanciful suggestions (for example: requiring at least a
single space between nibbles to help users identify input that is
truncated by a byte or two in case of a fudged copy-paste), but
they're not nearly as large confusion-eliminators.

I, too, am amazed!
