Since upgrading to OS X mavericks, the 'subl' alias frequently doesn't work.
The way it used to work: from the shell prompt, typing 'subl -n .' would open a new window in Sublime Text with the current directory in the sidebar.
The way it works now: from the shell prompt, typing 'subl -n .' switches focus to sublime but doesn't open a new window with the current directory. If no other windows are open (but ST2 is running) it will open a new window with no contents. Maybe one out of 10 times it successfully opens the directory in ST2. Specifying a file instead of a directory has the same effect (new window or no action, but doesn't open the file).
