Slight documentation bug on SWI Prolog website:

On the page

[https://eu.swi-prolog.org/pldoc/doc/\_SWI\_/library/plunit.pl](https://eu.swi-prolog.org/pldoc/doc/_SWI_/library/plunit.pl)

The top says:

> Unit testing environment for SWI-Prolog and SICStus Prolog.  
> For usage, please visit [section('packages/plunit.html')](http://www.swi-prolog.org/pldoc/package/plunit).

That URL should either point to

[https://www.swi-prolog.org/pldoc/doc/\_SWI\_/library/plunit.pl](https://www.swi-prolog.org/pldoc/doc/_SWI_/library/plunit.pl)

itself or maybe

[https://www.swi-prolog.org/pldoc/doc\_for?object=section(%27packages/plunit.html%27)](https://www.swi-prolog.org/pldoc/doc_for?object=section(%27packages/plunit.html%27))

This link works fine as far as I can tell. Why would it be wrong?

But it doesn’t. It leads to:

Because the final dot is included in the URL:

[http://www.swi-prolog.org/pldoc/package/plunit](http://www.swi-prolog.org/pldoc/package/plunit.)

vs

[http://www.swi-prolog.org/pldoc/package/plunit](http://www.swi-prolog.org/pldoc/package/plunit)

Sorr my initial links got messed up by markdown metacharacters. Fixed now.
