FindMPI: Fix documentation formatting

Adjust whitespace to make the output of "--help-module FindMPI" look
good.  Also separate the comment containing the copyright and license
notice so it does not appear in the documentation.

# - Message Passing Interface (MPI) module.

#=============================================================================
# - Find a Message Passing Interface (MPI) implementation
# The Message Passing Interface (MPI) is a library used to write

#
#=== Variables ===============================================================
# === Variables ===
#
# This module will set the following variables per language in your project,
# where <lang> is one of C, CXX, or Fortran:
#
# MPI_<lang>_FOUND TRUE if FindMPI found MPI flags for <lang>
# MPI_<lang>_COMPILER MPI Compiler wrapper for <lang>
# MPI_<lang>_COMPILE_FLAGS Compilation flags for MPI programs
# MPI_<lang>_INCLUDE_PATH Include path(s) for MPI header
# MPI_<lang>_LINK_FLAGS Linking flags for MPI programs
# MPI_<lang>_LIBRARIES All libraries to link MPI programs against
#
# Additionally, FindMPI sets the following variables for running MPI
# programs from the command line:
#
# MPIEXEC Executable for running MPI programs
# MPIEXEC_NUMPROC_FLAG Flag to pass to MPIEXEC before giving it the
# number of processors to run on
# MPIEXEC_PREFLAGS Flags to pass to MPIEXEC directly before the
# executable to run.
# MPIEXEC_POSTFLAGS Flags to pass to MPIEXEC after other flags.
# MPIEXEC_NUMPROC_FLAG Flag to pass to MPIEXEC before giving
# it the number of processors to run on
# MPIEXEC_PREFLAGS Flags to pass to MPIEXEC directly
# before the executable to run.
# MPIEXEC_POSTFLAGS Flags to pass to MPIEXEC after other flags
# === Usage ===
#
#=== Usage ===================================================================
# To use this module, simply call FindMPI from a CMakeLists.txt file, or
# run find_package(MPI), then run CMake. If you are happy with the auto-
# detected configuration for your language, then you're done. If not, you
# have two options:
#
# 1. Set MPI_<lang>_COMPILER to the MPI wrapper (mpicc, etc.) of your
# choice and reconfigure. FindMPI will attempt to determine all the
# necessary variables using THAT compiler's compile and link flags.
#
# 2. If this fails, or if your MPI implementation does not come with
# a compiler wrapper, then set both MPI_<lang>_LIBRARIES and
# MPI_<lang>_INCLUDE_PATH. You may also set any other variables listed
# above, but these two are required. This will circumvent
# MPI_<lang>_INCLUDE_PATH. You may also set any other variables
# listed above, but these two are required. This will circumvent
# autodetection entirely.
#
# When configuration is successful, MPI_<lang>_COMPILER will be set to the
# compiler wrapper for <lang>, if it was found. MPI_<lang>_FOUND and other
# variables above will be set if any MPI implementation was found for <lang>,

# When using MPIEXEC to execute MPI applications, you should typically use
# all of the MPIEXEC flags as follows:
# ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS ${MPIEXEC_PREFLAGS} EXECUTABLE
# ${MPIEXEC_POSTFLAGS} ARGS
# ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS
# ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS
# where PROCS is the number of processors on which to execute the program,
# EXECUTABLE is the MPI program, and ARGS are the arguments to pass to the
# MPI program.
#
#=== Backward Compatibility ==================================================
# === Backward Compatibility ===
#
# For backward compatibility with older versions of FindMPI, these
# variables are set, but deprecated:
#
# MPI_FOUND MPI_COMPILER MPI_LIBRARY
# MPI_COMPILE_FLAGS MPI_INCLUDE_PATH MPI_EXTRA_LIBRARY
# MPI_LINK_FLAGS MPI_LIBRARIES
#
# In new projects, please use the MPI_<lang>_XXX equivalents.
