Bug#1023310: josm: Debian version prompts for external updates even though that would break Debian

[David Calman]

Package: josm
Version: 0.0.svn18570+dfsg-1~bpo11+1
Severity: normal

Dear Maintainer,

I ran JOSM and it said to update to 18583, which it said was the newest
stable version. That's not even in sid yet, much less stable-backports.
Something official Debian materials say to do is "don't break Debian",
"don't make a Frankendebian", "always install from apt if it's there",
and so on. I wonder if someone more familiar with Debian policies than
me can upgrade the severity to serious upon finding chapter and verse.
