Bug 107128 [typing] Move lines destroys indentation of outcommented code
I20050811-1530 Move lines destroys the indentation of code that has been commented out. IMO, Move lines should never try to be smart about the contents of a commented section. It should just add/remove whitespace in front of the // (same behavior as when moving other statements). public class Klass { int bar; // void foo() { // System.out.println("foo"); // } } - select the 3 commented lines - press Alt+Up -> document looks like this (note the removed tab in fromt of System.out.pr...): public class Klass { // void foo() { // System.out.println("foo"); // } int bar; }
