[fetchmail]option to remove cleartext password from logs?

Dear fetchmail friends,
   is there some option that will prevent fetchmail to print passwords
as cleartext (replacing it with XXXXXXXX or PASSWORD or any other string)
in the logs of fetchmail -v ?
It is rather annoying to have the password in clear,
particularly so when someone may be snooping in your back
while you run fetchmail in a window, or when you keep logs in a file
to see if anything went wrong during batch processing.
It's insecure enough to have important secrets in one's .fetchmailrc;
it's worse if these secrets leak like crazy.

Property in ideas is an insoluble contradiction.  [He who complains of
"theft" of his idea] complains that something has been stolen which he
still possesses, and he wants back something which, if given to him a
thousand times, would add nothing to his possession.
