Synopsis: PetscErrorCode PetscOptionsTail(void)
Notes: Must be between a PetscOptionsBegin() and a PetscOptionsEnd()
Must be preceded by a call to PetscOptionsHead() in the same function.
This needs to be used only if the code below PetscOptionsTail() can be run ONLY once. See, for example, PCSetFromOptions_Composite(). This is a return(0) in it for early exit from the function.
This is only for use with the PETSc options GUI; which does not currently exist.
