Gentelmen, the "shr" program is mangling messages.

It could remove vital words, causing arguments:

"I did include the address!" "No you didn't." "Yes I did. Your mail
reader probably cut it out."

We're talking data loss here. It may still be on the disk, but not shown
to the user.

True, the HTML might not be perfect, but at least Chromium, Firefox,
etc. show it fine.

Hmmm, w3m -dump on the attachment shows the first URL in full.

KY> However shr renders it as:

KY> * 

KY> There lacks the "Hi, you have a new mail" message.  The return

OK I'll send the message,

I see.  But I'm sorry for my confusion; that extra text appearing
is not due to my change.  So, I'm closing this bug.  Thanks.
