Call ParseFinishLine() also for the last line in a file. This

patch differs from the previous one in that it calls the function
only when a real file hits EOF. The bodies of .for loops are also
handled as files, but for these we don't want to end a dependency block
on the 'EOF' as in:

foo:
	do-this
.for ...
	do-something
.endfor
	do-more
