I suppose actually I could just escape the tab in the C string. But as
Petr says, docparse is not mandatory so anything which can pass C
compilation, but fails docparse is likely to create trouble.

It would be possible to force running docparse and doing some validation
on the JSON. As this would not require any more dependencies. In fact it
would be nice to run docparse to produce just the JSON without having to
install asciidoc[tor].

The Makefile doesn't seem to allow this. Although it is quite easy to
compile docparse without it.
