deceptive mail and su

[Howard Johnson]

This conversation about su has me wondering:  What do people usually use
su for?  I see two commonly used functions here:  1) administrative and
maintenance functions (e.g. su news; ...) for required access privileges,
and 2) for someone else to do/show something (e.g. su - joe; ...; EOT).

It seems to me that su could be smart enough to distinguish between these
two uses (since it already has separate command sequences which are
documented).  Opinions?
