Comment(by mstone):

 Passing PATH through rainbow-easy seems like a good solution to Thomas'
 difficulty. I have therefore implemented this behavior in the 'ms/slo2199'
 topic branch in [1] and I have updated the (new) 'pu' proposed updates
 branch accordingly. Testing and review welcome.

 As for path lookup... my general feeling is that rainbow-run shouldn't be
 guessing about what path the user meant. In this world, rainbow-run should
 call execve everywhere and rainbow-easy should pass an appropriate path to
 rainbow-run, e.g., by delegating the lookup to "which". A topic branch
 containing patches to this effect would be most welcome.
