Re: RMAIL slows

[Richard Stallman]

These three show three different situations.  In one,
rmail-reformat-message has called delete-char.  In another,
rmail-reformat-message has called rmail-clear-headers.  The other is
in goto-address and not in rmail-reformat-message at all.

One of these is probably the thing that takes the extra time
that causes the slowdown.  What you need to do is figure out
which one it is.  Then please focus *only* on that case
and ignore the other cases.
