Interesting how one's perceptions change. My immediate reaction was
"but the command is 'MAIL', so you should have what you want already",
but when I went to doublecheck on the code that I wrote 10 years ago, I
see that I treat the whole of "MAIL FROM:" as the "command". The RFC
does seen to indicated that only one space is allowed between MAIL and
FROM:, fortunately.
Another thought occurs to me: your patch would also allow you to
distinguish between HELO and EHLO, so that's another benefit.
