PetscEmacsClientErrorHandler
Error handler that uses the emacsclient program to load the file where the error occured. Then calls the "previous" error handler.

Notes
You must put (server-start) in your .emacs file for the emacsclient software to work
Most users need not directly employ this routine and the other error
handlers, but can instead use the simplified interface SETERRQ, which has
the calling sequence
SETERRQ(PETSC_COMM_SELF,number,p,mess)
Notes for experienced users
Use PetscPushErrorHandler() to set the desired error handler.
Developer Note
Since this is an error handler it cannot call CHKERRQ(); thus we just return if an error is detected.
