Pretty much everything that you described above + output of /etc/motd,
setting terminals parameter depending of terminal type (there are
several standard ones that are normally shipped with systems) happens
under

case $0 in
  -sh|-ksh|-jsh|-rsh)

Do not ask me why; I have not written it and have no chance to change
it. Actually, since I'm running under X I do not care about /etc/profile
anymore; it is sourced by Xsession so environment gets set up anyway (to
account for optional software that may add something to /etc/profile)
and I do not care about setting terminal under dtterm :-)

So, unless this is an issue on more than one system, we can probably
ignore it. But if we are going to locally emulate /bin/sh - why not
pretend, we *are* -sh? :-)
