To work around the issue, I just wrote a stupid sed script. Of course,
it means that if we encounter again the issue on some other docs, we'll
have to update it. In other words, it's neither robust nor a proper
long-term fix. Just a temporary hack.

Also fixing this issue, I encountered another bug, this time in meson,
which changes backslashes in slashes on 'command' arguments, in a
completely uninvited manner! The only workaround to this is apparently
to call an external script, which is ridiculous for such a basic stuff.
But well… here is why I implement this with a script, instead of
directly calling sed in the meson 'command'.
