Bug fix for makescript

[chris at umcp-cs.UUCP]

Oops, seems a bug crept into my makescript program.  Here's the problem,
and the fix.

Problem:
	makescript foo File_Without_Leading_Slash

generates an error about "can't change to directory /usr/foo
".  This is because there's a newline left in the directory returned
by /bin/pwd.

Fix:
	add (after the first fread call) the two lines

	if (WDir[0])
		WDir[strlen (WDir) - 1] = 0;

and the problem should go away.
