Bad link to / has confusing error message

[not-my-profile]

hyperlink apparently strips leading slashes which however results in a confusing error message when an index.html file in the base-path is missing:

% mkdir /tmp/test
% echo '<a href=/>test</a>' > /tmp/test/foo.html                   
% hyperlink /tmp/test

/tmp/test/foo.html
  error: bad link 

Found 1 bad links

Notice that it doesn't say what the bad link is.

tempted to fix this by prepending / when formatting the error message
