This adds a line break between each result address in the output of the
lldb command target modules lookup. Before this change, a new address
result will be printed on the same line as the summary of the last
result, making the output difficult to view.
Also adds a test for this command.
This might be better off as an --implicit-check-not argument to FileCheck. As it stands now, it will only check that ignoreThisFunction does not appear at the very end of the output.
