Eclipse / PyDev - remove path from editor tabs when two files with the same name are open

I am currently using Elipse Luna and I am trying to figure out how to remove the pathname in editor tabs when multiple files with the same name but different directories are opened (see screenshot).

In other words, keep the filename, but remove it in parentheses.

I've done this in the past with previous versions of Eclipse, but I can't remember how I did it my whole life. I just find that the path names take up a lot of real estate in my editor and it doesn't take long before the tabs are hidden.
