OK!  Well, actually, I need a function that works something like this:

(count-lines-in-file FILENAME)

where FILENAME is some sort of path name, like
"/windows/dansstuf.txt", and the result being that the number of lines
(i.e. newline characters) in DANSSTUF.TXT (or whatever) is returned
from the "count-lines-in-file" function.
