Bug#869539: love.keyboard.isDown("lctrl") always returns false

[Phil Hagelberg]

Package: love
Version: 0.9.1-4
Severity: important

After upgrading to Debian Stretch, I have observed that no matter
whether I press the left ctrl key, the function love.keyboard.isDown("lctrl")
always returns false. Right ctrl is unaffected. Note that this is
likely a problem with one of love's dependencies, since it affects
every version I have tried, including 0.10.2 and current trunk, and
these versions worked fine on jessie.

To reproduce, run this:

cd /tmp
mkdir ctrltest
cd ctrltest
echo 'love.keypressed = function(k) print(k, love.keyboard.isDown("lctrl", "rctrl") and "control") end' > main.lua
love .
