THe colons are only needed when you type the command from a shell so that the 
shell (in which you type the whole command) knows that: 
	make -f admin/Makefile.common cvs
is the third argument and not argument 3, 4, 5 and 6.

In KProcess you do something like:
process << "/bin/sh" << "-c" << "make -f admin/Makefile.common cvs";
So KProcess knows that this are 3 arguments and not 6. It then passes these 3 
arguments to execvp().

Waldo
