mush fix

[Greg Lee]

I use mush to review batches of news articles, and sometimes the
body of a follow-up begins "From article ...".  Of course that
fouls up the mechanism for dividing one piece of mail from another.
The symptom is that mush reports an error -- bad date.  The following
minor change seems to fix the problem.  The patch is for mush v 6.3.
