[OMPI users] Typo in mpirun man page

[Jeremiah Willcock]

In the mpirun man page in Open MPI 1.3.4, in the "Current Working 
Directory" section, there is the following sentence:

"""
If they are unable (e.g., if the  directory  does  not  exit  on that 
node), then Open MPI will use the default directory determined by the 
starter.
"""
I believe "exit" there should be "exist".
