Here's one more problem, a more serious one.  The message reproduced
below, posted today to emacs-devel, is by default displayed with no
body at all for the 1st part, like this (indentation added):

I guess we need to handle parts with no Content-Type at all?

Here's the original message, copied from the RMAIL buffer after
toggling the display with `v' (again, indentation added):

  Ok, just recompiled emacs with dumping support, and running

    $ emacs -Q --batch --eval \
      '(dump-emacs "./demacs" "/usr/bin/emacs")'

  on the NanoNote gave me:

    [..]
    Loading ediff-hook...
    Finding pointers to doc strings...
    Finding pointers to doc strings...done
    emacs: Can't allocate buffer for /usr/bin/emacs

  So it wants to pull a full copy of the emacs binary into memory?
  This problem I can workaround by changing the Linux overcommit setting,
  but then dumping fails with another problem:

    $ echo "1" > /proc/sys/vm/overcommit_memory=20
    $ emacs -Q --batch --eval \
       '(dump-emacs "./demacs" "/usr/bin/emacs")'

    [..]
    Finding pointers to doc strings...
    Finding pointers to doc strings...done
    emacs: Program segment above .bss in /usr/bin/emacs

  So what's that supposed to mean?=20=20

  cheers,

  David
