Fix thanks to Arne Bernin <arne@matrix.loopback.org>
* Added support for "sh -c command args...", thanks to
Marius Groeger <mgroeger@sysgo.de>
+ * Added support for being a login shell, so things like
+ '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
+ invoke the shell. Now you can use BusyBox as a login shell.
