When re-running (say)
uru auto with a $PATH, it seems everything up-to the "_U_" entry is deleted unceremoniously, and the new Ruby's path added.
This means I have to re-add any items that I may have added, but also causes some headaches on Mac OSX; OSX doesn't run the User's local .rc script when logging-in, so you have to re-run it before certain apps to allow certain app's to be easy to find (e.g. IDE's) and sometimes again within tools like Emacs for it to find certain tools.
Is there any way Uru can detect only it's own updates to the $PATH and update them in-place, similarly to tools like Chruby and RVM?
