ionic cordova wrapping swallows "Terminate batch job (Y/N)?" prompt, causing e.g. cordova run processes to not really stop and cause increasing port numbers to be used

Compare what happens when you hit Ctrl + C when running ionic cordova run ... vs. when running cordova run ...:

On the pure cordova command you get an additional prompt:

^CTerminate batch job (Y/N)? y

When you immediately run the same command again after killing it, it should just start a server again on the same port, 8000 by default. But with ionic cordova ... you get increasing port numbers:

200 /index.html (gzip)

vs.

PS C:\Projects\Ionic Demo Projects\browserTest2> cordova run browser
startPage = index.html
Static file server running @ http://localhost:8000/index.html
CTRL + C to shut down
200 /index.html (gzip)
...

^CTerminate batch job (Y/N)?
^C
PS C:\Projects\Ionic Demo Projects\browserTest2> cordova run browser
startPage = index.html
Static file server running @ http://localhost:8000/index.html
CTRL + C to shut down
304 /index.html
...
404 /screen

That this "Terminate batch job" prompt is important can be deduced from what happens when you first run ionic cordova run with increasing port numbers, then cordova run once with another +1 port and kill it with the prompt, after that the next run will get the initial port number again:

...
PS C:\Projects\Ionic Demo Projects\browserTest2> cordova run browser
startPage = index.html
Static file server running @ http://localhost:8003/index.html
CTRL + C to shut down...
^CTerminate batch job (Y/N)?
^CThe system cannot open the device or file specified.
PS C:\Projects\Ionic Demo Projects\browserTest2> cordova run browser
startPage = index.html
Static file server running @ http://localhost:8000/index.html
CTRL + C to shut down
...

Is this just cordova run browser?

This is not our output:

Static file server running @ http://localhost:8000/index.html
CTRL + C to shut down

Good point. Will look into that.

Yep. So if you don't care about cordova-browser, you don't care about this issue.
