handle/make/file: do multiple project arguments

At the end of the function, this script will now
run itself again if there are more arguments. This
enables the following:

./handle make file -c project1 project2 project3

Whereas previously, it could only do this:

./handle make file -c project1

Substitude -b and it's the same.
