We can use

To set and read the synctex tag.
But if we wrap this into a macro, things get broken and the synctex tag is not
changed.
```
\def\test{\directlua{tex.set_synctex_tag(421)}}
\test
\directlua{print('421=',tex.get_synctex_tag())}
\bye
```
For synctex_line there is no such problem.
Is this a bug or a feature ?
feature ... but mostly macro package related as that is responsible for
the catcode of _ which is stored in the macro body
