Bug#983847: querybts -m does not escape "\nFrom " sequences; breaks mutt

["Trent W. Buck" <trentbuck@gmail.com>]

Package: reportbug
Version: 7.10.2
Severity: normal
File: /usr/bin/querybts

These commands are bugged:

    bts show -m 928175
    querybts -m 928175 >tmp.mbox && mutt -f tmp.mbox

This is because an email in that mailbox containes a byte sequence "\nFrom ".
This sequence is used by mbox to delimit messages, and must be escaped.

(Typically this is done by changing "\nFrom " to "\n>From ", though
IIUC this will break DKIM validation.)

This might need to be fixed on the server side (i.e. in debbugs).
If so, please reassign as appropriate.
