Comment(by mnislaih):
Previously the enclosing function for a tick wrapping an entire function
definition f was f itself.
With this patch, the enclosing function is attributed to be the module
itself.
The previous output was nicer to the user, but one could argue that the
new output is more correct.
In my opinion it is not a big deal, and changing it to behave as before
would involve having a hybrid approach to resolving the enclosing decl of
a tick, which does not sound appealing at all.
So I would say the new output is OK.
