<div class="moz-cite-prefix">(I'm not sure what the
settings/commands are in the email application you use ("foxmail"
apparently), but please configure it / use it such that you
*reply* to messages rather than adding text onto a *forwarded*
copy of the message you mean to reply to - in a "reply",
everything in the original message has "> " (or something
similar) added to the beginning of each line so that you can
insert your own text in the middle and it will be easily
recognizeable (no markers). Also, sending your messages in plain
text format would be greatly appreciated (some readers of the
mailing list will not be able to read your messages since they are
in html-only, so you are lowering the visibility of your
questions.)<br>

Well, not exactly, but I think I replied before I had enough coffee.
You can disregard that entire paragraph, as it was based on some old
memory of [something, not sure what right now] and experiments I
performed just now verified that it is *not* the case for tap
devices.<br>
