[PATCH weston 2/2] input: Update to-be-restored focus when unfocused

Tue Sep 18 00:04:16 UTC 2018

It took me longer than I hoped to get back to this, but I have now tested
Quentin Glidic's two patches (the revert followed by the revised fix) plus
my "Restore keyboard focus after VT switch", applied to Weston 4. With all
three patches applied, Weston passes my tests. Hooray!

And just to be sure, I verified that applying Quentin's patches without
mine do _not_ pass my tests. So Quentin's patches don't interfere with mine
(good!) but also don't supersede mine, despite how Patchwork apparently got
set.

Thanks everyone for keeping this going and working out the right details!
