Doubling up inputs in iTerm2

[OaHolroyd]

When I run notcurses-input using iTerm2, all of the inputs are doubled up. eg, after pressing the 'a' key once, I get

 sacuhmx.L ASCII: [0x61 (097)] 'a'
 sacuhmx.P ASCII: [0x61 (097)] 'a'

Whereas using the default Terminal I just get

 sacuhmx.u ASCII: [0x61 (097)] 'a'

This also applies to mouse-button clicks.

Additionally, when I exit with ctrl-D, in iTerm2 it prints 7442;1:3u, and all subsequent keypresses are broken until I restart the session. With the default Terminal it works as expected.

Potentially the same issue as #2811?

note the different control prefixes (the left column):

sacuhmx.L ASCII: [0x61 (097)] 'a'
 sacuhmx.P 

the first event is the key press. the second event is the key release. this is not a bug.

if you don't care about one or the other event, just filter them out using the evtype field of nckey.
