Duplicate explicit target name for links

[matthieucan]

Hello, When a markdown document contains more than 1 link whose name is identical, m2r2 generates those links but fails to make them anonymous references. According to https://github.com/sphinx-doc/sphinx/issues/3921 this doesn't follow ReST specs.

How to reproduce:

% cat foo.md
[foo](https://foo.bar)
[foo](https://bar.foo)
% m2r2 foo.md
% cat foo.rst

`foo <https://foo.bar>`_
`foo <https://bar.foo>`_
% rst2html.py foo.rst > /dev/null
foo.rst:3: (WARNING/2) Duplicate explicit target name: "foo".

Hello @matthieucan, I think you'd want to run as m2r2 --anonymous-references foo.md ?

Hi @CrossNox, thank you very much, that fixed my problem! :+1:

Is it possible to enable anonymous references when using .. mdinclude within another rst document?

For anyone else who had this issue and wondering how to set the value in conf.py when used with sphinx:

m2r_anonymous_references = True

The sphinx option names can be seen here: https://github.com/CrossNox/m2r2/blob/0408d7acea843485d9ff42ee08a105a79f045493/m2r2.py#L675C27-L675C51
