  This simple patch updates the documentation of "help run" in order to
mention that the shell used to start the inferior comes from the
$SHELL environment variable.  It also mentions that this behaviour can
be disabled by using the "set startup-with-shell off" command.

OK?

Yes, but instead of 'see the "$SHELL" environment variable', I'd
suggest to say 'specified by the "$SHELL" environment variable'.

Thanks.
