Here's a fun (I mean annoying) little fact I found out today: if you use CTRL-/ to uncomment multiple lines of code that were commented out with the old editor, all the functions code is now only indented by one space!
Old Editor:
//function foo() {
// var a = 1;
//}
New editor
// function foo() {
// var a = 1;
// }
The new editor puts a space after the comment, so if there is no space when you remove the comments (inserted by the old editor) it takes it from within the function leaving only one space indent.
I don't think I could cope with a world where I have functions with only one space indents!!!
