This was easier to fix than I thought. Yet another issue resolved, yay!

  * resolve issue2275: ignore symlinks as repo paths even when the index is used
  
  It was necessary to fix the last test scenario in the script (removing a
  recorded file and replacing it with a symbolic link to a non-existing file)
  because what the script expected here was not what we want, namely that the
  symbolic link is treated as if it wouldn't exist.

  * add a warning when the index code ignores a symlink
  
  The solution is unfortunately not perfect: some commands, notably
  'darcs wh -l' issue the warning twice per link. I think this is because of
  the implied '-s', since 'darcs wh -l --no-summary' displays it only once.

The code change looks plausible. 

I haven't read through the issue2275 discussion and the new test code in
detail to make sure the two agree.
