Possible typo in the function "tickit_watch_io"

[brickpool]

The AND operation of the flags is performed using an unusual construct (TICKIT_BIND_UNBIND|TICKIT_BIND_UNBIND).
To me, this looks like a typo in the function tickit_watch_io. This should probably be watch->flags = flags & (TICKIT_BIND_UNBIND|TICKIT_BIND_DESTROY), see

libtickit/src/tickit.c

Line 469 in 9bc5e30

watch->flags = flags & (TICKIT_BIND_UNBIND|TICKIT_BIND_UNBIND);
