Change 15370
Minor tweaks to p4_vars.template:
* Added comments for MAILTO and MAILFROM, clarifying that MAILTO can have a
comma-delimited list (no spaces) and MAILFROM must be a single address.
Cleanup: Added 'export' declarations so a few extra lines containing only export
declarations could be deleted. Collateral benefit is that CUT, GREP, and PS are
now exported consistently along with their friends AWK, SED, MAIL, DF, ID, etc.
