[SM-PLUGINS] preview_pane patch of src/read_body.php has bug

[Sharon S. <st...@so...>]

Hello,
    I am running the squirrelmail 1.4.23, 20170203_0201-SVN
on a CentOS 7 linux system.
    I have found that the  plugin preview_pane V1.2 patch for
src/read_body.php
doesn't work properly.  If you DO NOT use the preview pane, you do not
see the following options at the top of your message any longer.

Message List|Unread|Delete   Previous|Next   Forward|Forward as
Attachment|Reply|Reply All

...hence you cannot reply to a message unless you use the preview_pane.

   Once I realized it was the preview_pane plugin causing it, I brought over
an old version of src/read_body.php  from squirrelmail-1.4.23,
20130620_0200-SVN
as a test, and all seems to worksfine.

  I was wondering if anyone is maintaining this plugin any longer.  I first
saw this commented on in 2014 in the archives but nothing since. Our
users are used to having this option.  Should I just run with the old
read_body.src ?
What will not work if I do?

Thank you for any insight you may have.

Aloha, Sharon Stahl
