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.

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.
