Variable expansion happens first:
	someprog --greeting Hello Karsten
then tokenising, so someprog get three arguments:
	1. --greeting
	2. Hello
	3. Karsten
whereas you want it to get two arguments:
	1. --greeting
	2. Hello Karsten
in which case you need double quotes around $C to prevent it from being
split into multiple tokens:
	someprog --greeting "$C"
