Then, I believe, the "other mailers" are broken; a message boundary in
the mbox file format is defined to be "From " immediately following two
consecutive newlines (with an implicit message begin at the beginning
of the file). Always has been. If some UAs mistake "From " after one
(but not two) newlines for a message boundary, then their mbox parsing
code is simply broken, as much so as if it mistook any other string for
a message boundary.

That is correct, at least as far as what I've seen goes. (Is it when
_reading_ root's .forward, or when _executing pipes therefrom_?)
