Review comment:
       @neilcsmith-net please give it a try first and test it. This PR should 
restore the original behavior. We can improve discoverability of the multi line 
feature later - this has low priority for me. A hidden feature is not a bug, 
this PR fixes a regression caused by 
https://github.com/apache/netbeans/pull/3393.
   
   just to be to be sure i repeat: this PR changes nothing regarding 
discoverability, it restores original behavior so that if you are used to Enter 
as action trigger, you can keep using it.
