-    # BAW: According to

-    # the only portable, reliable way to find message delimiters in a BSD (i.e
-    # Unix mailbox) style folder is to search for "\n\nFrom .*\n", or at the
-    # beginning of the file, "^From .*\n".  While _fromlinepattern below seems
-    # like a good idea, in practice, there are too many variations for more
-    # strict parsing of the line to be completely accurate.
-    #
-    # _strict_isrealfromline() is the old version which tries to do stricter
-    # parsing of the From_ line.  _portable_isrealfromline() simply returns
-    # true, since it's never called if the line doesn't already start with
-    # "From ".
-    #
-    # This algorithm, and the way it interacts with _search_start() and
-    # _search_end() may not be completely correct, because it doesn't check
-    # that the two characters preceding "From " are \n\n or the beginning of
-    # the file.  Fixing this would require a more extensive rewrite than is
-    # necessary.  For convenience, we've added a PortableUnixMailbox class
