There is a third way, which is the one that is relevant here -- the
shell automatically sources the script.  This is always done for
~/.profile in a login shell and may also be done for some enhanced
shells on a per-interactive-shell basis.  These scripts are supposed
to be executed in the current context of the shell, so their effects
are supposed to stick.
