4261341281 umount: ignore -c

9c8e94bc0a ash: fail if 'shift' operand is out of range 
If the numeric argument passed to ash's 'shift' built-in is greater than
'$#' the command performs no operation and exits successfully. It should
return a non-zero exit code instead:

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#shift

This is consistent with bash and hush.

952d5a6024 applets/install: accept more than one install option 
Currently, it is impossible to pass more than one option to the isntall
script, so it totally prevents using --noclobber.
