If you're asking what that format string does: if there's an Fcc:
header field in the message being replied to, it will use its contents
in the draft. If there isn't an FCC: header field in the message being
replied to, it will do nothing.
That's not exactly correct. It's really there to make the -fcc switch
to repl work. But if you don't include a -fcc switch, it will take the
value of any Fcc: header and place it in your outgoing draft.
Like you, I think that's a terrible idea. I think that was unintentional.
We should probably clear those pseudo-components out in replsbr.c so
that they always show up as blank if they aren't included on the command
line.
