# An overridable mechanism to test for From-line-ness. You can either
# specify a different regular expression or define a whole new
# _isrealfromline() method. Note that this only gets called for lines
# starting with the 5 characters "From ".
#
# BAW: According to
#http://home.netscape.com/eng/mozilla/2.0/relnotes/demo/content-length.html
# 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
# which does no checking of the format of the 'From' line.
