Thanks for your help. What you describe is what I thought should
happen. But I couldn't figure out how to join the paths. It always
looked right: I'd do debugging runs that simply printed out the
command it was supposed to execute, and I could get results like

'ln -s ./wombats/habitat/burrows.html ./wombats/habitat/Burrows.htm'

(which I think should work) but when I ran this through os.system(),
it failed every time. So did every other variant I could think of
except changing to the directory where the file was and linking
without any paths involved.
