Problem with the documentation of Mesh_3

[albert-github]

When looking at the documentation of Mesh_3 (https://cgal.geometryfactory.com/CGAL/Manual_doxygen_test/CGAL-6.0-I-80/master/Mesh_3/classCGAL_1_1Polyhedral__mesh__domain__with__features__3.html) we see that a lot of the documentation is duplicated e.g. (but there is more and it is also with the 1.8.13 and 1.9.6 runs)

I just looked at the detect_borders() ( as I saw here "Detects" and "detect" so easy search) and found these texts in:
Mesh_3/doc/Mesh_3/CGAL/Polyhedral_mesh_domain_with_features_3.h and Mesh_3/include/CGAL/Polyhedral_mesh_domain_with_features_3.h

Removing the comment from Mesh_3/include/CGAL/Polyhedral_mesh_domain_with_features_3.h already improved the situation, though I think the real problem is conceptual, we have double definitions of the functions (Mesh_3/doc/Mesh_3/CGAL/Polyhedral_mesh_domain_with_features_3.h and Mesh_3/include/CGAL/Polyhedral_mesh_domain_with_features_3.h) and both parts are added as input as part of the INPUT for doxygen, see also doc/Mesh_3/Doxyfile.in where quite a list of files is present.

All the duplicate definitions should have been removed from doc by PR #7445
Did something go wrong since then?

The PR #7445 indicates that the code in Mesh_3/doc/Mesh_3/CGAL/Polyhedral_mesh_domain_with_features_3.h should have been removed, I did a quick git log Mesh_3/doc/Mesh_3/CGAL/Polyhedral_mesh_domain_with_features_3.h but didn't find any indication of the PR #7445 and did some further investigations (I had a suspicion, don't know why but probably because it was very large and and a number of merges with the master, on which PR might cause the problem).
It looks like that #7395 is the culprit.

Merge pull request #7576 from albert-github/feature/issue_7395

issue #7395 Improvement of layout of model relations

as here there are 2 files added (and is very unlikely I would add files in the "kernel" of CGAL) i.e.

Mesh_3/doc/Mesh_3/CGAL/Polyhedral_mesh_domain_3.h
Mesh_3/doc/Mesh_3/CGAL/Polyhedral_mesh_domain_with_features_3.h

I locally removed these 2 files and ran the documentation build procedure on the Mesh_3 directory and the documentation looks OK (visual inspection). I also ran my link checker (that actually detected the problem) and also here I didn't see any problems regarding Mesh_3.

• Should I make a PR removing these 2 files?

Sure, feel free to go ahead!
Thank you for the report and diagnostic
