Bash usually doesn't run any startup files when invoked non-interactively,
and `-c command' is such a case. The shell tries to guess when it's run
by `su -' and run the startup files, but unless `su' indicates this in some
way -- usually by setting argv[0] to `-su' -- bash has no way of knowing
this.
