mutt-1.5.17: MIME boundaries should not be displayed on the only text/plain part

[vasily@…]

Package: mutt
Version: 1.5.17
Severity: normal

-- Please type your report below this line

Alpine, a successor of Pine MUA, by default sends 8-bit mail as MIME
multipart/mixed with only one text/plain part. For example:

,----
| [...]
| User-Agent: Alpine 0.99999 (DEB 796 2007-11-08)
| MIME-Version: 1.0
| Content-Type: MULTIPART/MIXED;
| BOUNDARY="-1463811583-823278545-1198451178=:5415"
|
|   This message is in MIME format.  The first part should be readable
|   text,
|   while the remaining parts are likely unreadable without MIME-aware
|   tools.
|
| ---1463811583-823278545-1198451178=:5415
| Content-Type: TEXT/PLAIN; format=flowed; charset=KOI8-R
| Content-Transfer-Encoding: 8BIT
|
| ôÅÓÔ
| ---1463811583-823278545-1198451178=:5415--
`----

Mutt displays this message correctly, but it prepends the display with a
text/PLAIN boundary. This style:

,----
| [...]
| User-Agent: Alpine 0.99999 (DEB 796 2007-11-08)
|
| [-- Attachment #1 --]
| [-- Type: text/PLAIN, Encoding: 8bit, Size: 0.1K --]
|
| ôÅÓÔ
`----

My suggestion is that Mutt really should not display this boundary if
the message has an only text/plain part.
