Thank you for reporting that and for taking the time to prepare a patch.
Are you interested in making it a complete patch?
Since it is a bug fix, the patch should add an entry in the NEWS file.
Each bug fix also deserves regression tests: tests that fail before
and succeed after the patch is applied.
Will this patch have to take into account whether the
--follow-symlinks command-line option is specified? (haven't looked
If so, then there should be in-place tests that exercise this, both
with and without that option.

Finally, for each bug fix, we try hard to identify the released
version in which the bug was introduced (mention that in NEWS), and
the actual commit (mention that in the commit log for the patch).

Thanks again for the report and patch.
No obligation on your part to do any of the above.
Just outlining what's required, in case you're inclined.
If you don't do it, someone else will.
