scheibelp 31c5467f56 Add back help placeholder for "spack load" (#6127) ... Fixes #6126 #3183 removed the print_help function from the "modules" module. This adds it back so that if a user invokes 'spack load foo' without having sourced an environment setup script, they will be prompted to do so. This also improves the placeholder message to tell the user to invoke 'spack' as shell function rather than as an executable.		2017-11-06 11:03:36 -08:00
