Re: upper case in command and end of sentence

[Karl Berry]

    @commands like @emph, @asis... do not change anything compared with 
    text.  A period after a lower-case letter leads to double spacing,
    after an upper case letter simple spacing.

Shouldn't @footnote follow this rule too?  I don't see any obvious
reason why it should be treated differently than other non-code
commands.  Indeed, I think a footnote on someone's initial is actually
more plausible than using @emph or the like on an initial ... not that
any of it is very likely.  Donald address@hidden Knuth ...
