The traditional syntax of su(1m) is like this (quoted from Solaris'
manual page):
Any additional arguments given on the command line are
passed to the new shell. When using programs such as sh , an
arg of the form -c string executes string using the shell
and an arg of -r gives the user a restricted shell.
In GNU su(1m), the meaning of -c has been hardcoded. This is
incompatible with traditional behaviour. Everything after the
username should be used as the argv for the login shell. With the
current syntax, it is impossible to do "su user -r" or "su user
-login".
