Thanks for the bug report. The code currently calls stat() to check whether
it's working on a regular file, and craps out if it isn't.  So arguably we
should be using lstat() and failing in this case instead of stomping on the
symlink.  Or do you expect the code to chase the link and replace the symlink
destination file? I think the latter is probably too much to ask...
