handle debug output messing up jbangdev

[maxandersen]

if you run with JBANG_JAVA_OPTIONS=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5555

an error occurs like:

/Users/manderse/code/jbangdev/jbang/build/install/jbang/bin/jbang: line 230: exec: Listening: not found

because the output contains the following:

Listening for transport dt_socket at address: 5555

I wonder if we could strip out first line if it starts with "Listening" or we should simply just execute the last line ?

That might be doable on Linux and Mac, but really hard on Windows. It's already a miracle it works on Windows anyway.

Btw, the solution is to add quiet=y to the options.
