It's just to launch the editor from the command-line.

IT's nothing new - sublime text 2 (at least on OS X) had the "subl" command so you could launch an edit session from the cli.. I assumed the rest had the same.

It's certainly not a new feature or anything to celebrate.

It is new on Windows.

not so much, you could always do sublime somedirectory and it will open it. It appears the novelty is the --help option and more importantly the --wait option, so you could include sublime in a script workflow (as a git commit editor ?)
