Yeah, I looked into that for someone a while ago, and that doesn't work in
all cases. For example:

1. xdm
   The `setenv' capability doesn't work in xdm (the code just won't work
   as it stands); and in any case, xdm prefers a different method for
   setting PATH and env. (the `DisplayManager.*' resource settings).

2. su
   The default PAM variant does honour `setenv', but, the non-PAM one
   doesn't look like it does (it only does PATH).

3. sudo/doas/...
   3rd-party programs don't seem to grok `setenv'

OTOH, all of these, if they use PAM, do seem to call pam_getenvlist()
and use properly the returned variables.
