This series looks good to me. 

Except the reference to _POSIX_ page. One knows how consistent these
specifications are; alternative:

http://pubs.opengroup.org/onlinepubs/009695399/utilities/command.html

mentions additionally that -v flag
"(On systems supporting the User Portability Utilities option.)" 

Also, we don't give such a treatment to other command either; I'd rather
see RST2MAN=rst2man, RST2MAN=rst2man.py *and* RST2MAN= lines used
instead -- the last to set RST2MAN to empty string instead of being unset.
