Subject: apt: newline in Suites field in deb822 sources format causes apt to hang

Package: apt
Version: 1.6~alpha4
Severity: normal

When I include a newline in the Suites field in the deb822 sources
format, `apt update` hangs at the end of the download phase:

pabs@chianamo ~ $ chdist create test
Now edit /home/pabs/.chdist/test/etc/apt/sources.list
Run chdist apt test update
And enjoy.
