Quote and concatenate arguments for use in Bourne shell.
Each argument is quoted separately, and then all are concatenated
with spaces. If an argument is an array, the elements of that
array is interpolated within the rest of the arguments; this makes
it possible to have an array of arguments and pass that array to
shellquote instead of having to specify each argument
individually in the call.
