There is a family of incompatible mbox formats for storing mail; see
http://homepage.ntlworld.com./jonathan.deboynepollard/FGA/mail-mbox-formats.html
for all the details.
Examining unrmail.el from Gnu emacs 24.0.50.1 (lines 228-231):
;; ``Quote'' "\nFrom " as "\n>From "
;; (note that this isn't really quoting, as there is no requirement
;; that "\n[>]+From " be quoted in the same transparent way.)
clearly shows that Rmail 23 is using the mboxo format.
Unfortunately, this is known to be a bad format because it
irreversibly alters messages. I strongly recommend switching to a
format like mboxrd, which does not have this problem.
(In particular, any line in a message body starting with "From " is
changed to ">From " in a nonreversible manner; this will screw up MIME
attachments, among other things, with nonzero probability.)

PS, the documentation needs to explain which mbox format is used, rather
than saying "the standard mbox format", of which there is no such thing.
