A BAD SIGNATURE only means the email was changed/modified in the two
sentences above the extra space modified the original text.  Plain and
simple.
You could also rearrange the sentence entirely and still convey the
same thought; but, that would still mean the text was modified.

c.  All good men, now is the time to come to the aid of the party.

Still conveys the same thought however I would still want this to fail
the verification process.
