Hmm, that's not how I read
<http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00923.html>.
I understood the argument to be that a buffer must contain at most
MOST_POSITIVE_FIXNUM - 1 bytes due to other reasons, but it's OK
to have "a string whose length is MOST_POSITIVE_FIXNUM", i.e.,
(= (length STRING) most-positive-fixnum), because we already check
buffer sizes before inserting strings. If you
count the trailing byte, the length of the underlying C character
array would be MOST_POSITIVE_FIXNUM + 1.
I'll CC: this to emacs-devel just in case I misinterpreted that.
