Be lazy converting markers to integers, bytecode_{arithcompare,arithop}().
src/ChangeLog addition:
2013-12-15 Aidan Kehoe <kehoea@parhasard.net>
* bytecode.c (bytecode_arithcompare):
* bytecode.c (bytecode_arithop):
Call promote_args_lazy () in these two functions, only converting
markers to fixnums if absolutely necessary (since that is ON with
large, mule buffers).
* data.c (BIGNUM_CASE):
* data.c (RATIO_CASE):
* data.c (BIGFLOAT_CASE):
* data.c (ARITHCOMPARE_MANY):
Call promote_args_lazy () here too if WITH_NUMBER_TYPES is defined.
We're not doing the equivalent with the non-NUMBER_TYPES code, but
that's mostly fine, we are doing it in the bytecode.
* number.h:
* number.h (NUMBER_TYPES):
* number.h (promote_args_lazy):
Add this, returning LAZY_MARKER_T if both arguments are markers
that point to the same buffer.
tests/ChangeLog addition:
2013-12-15 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Test arithmetic comparisons with markers, check the type of the
returned values for #'min and #'max.

@node Reading Mail, Calendar/Diary, Sending Mail, Top @chapter Reading Mail @cindex mail @cindex message XEmacs provides several mail-reading packages. Each one comes with its own manual, which is included in each package. The recommended mail-reading package for new users is VM. VM works with standard Unix-mail-format folders and was designed as a replacement for the older Rmail. XEmacs also provides a sophisticated and comfortable front-end to the MH mail-processing system, called @samp{MH-E}. Unlike in other mail programs, folders in MH are stored as file-system directories, with each message occupying one (numbered) file. This facilitates working with mail using shell commands, and many other features of MH are also designed to integrate well with the shell and with shell scripts. Keep in mind, however, that in order to use MH-E you must have the MH mail-processing system installed on your computer. The @dfn{Everything including the kitchen sink} package @samp{Gnus} is also available as an XEmacs package. Gnus also handles Usenet articles as well as mail. @samp{MEW} (Messaging in the Emacs World) is another mail-reading package available for XEmacs. Finally, XEmacs provides the Rmail package. Rmail is (currently) the only mail reading package distributed with FSF GNU Emacs, and is powerful in its own right. However, it stores mail folders in a special format called @samp{Babyl}, that is incompatible with all other frequently-used mail programs. A utility program is provided for converting Babyl folders to standard Unix-mail format; however, unless you already have mail in Babyl-format folders, you should consider using Gnus, VM, or MH-E instead.
