Control: affects -1 + src:lua-readline
I'd like to upload lua-readline with a bugfix for #1034078 (see [1]).
[ Reason ]
This upload fixes #1034078. The patch is made upstream and taken
from newly released version 3.3.
[ Impact ]
This bug is a regression in version 3.2 which significantly
worsens user experience (standard Ctrl+D isn't interpreted as EOF).
[ Tests ]
There aren't automated tests, but manual testing using upstream test
code doesn't reveal any other regressions/bugs.
[ Risks ]
The code change is trivial, the bug currently affects the prosody
packhage in a way that its admin cannot simply exit from the
prosody server management console.
[ Checklist ]
[+] all changes are documented in the d/changelog
[+] I reviewed all changes and I approve them
[+] attach debdiff against the package in testing
