Hi Junsong,

I suspect that this simply comes from the fact that ocamldoc started out as
a separate project and thus had to develop its own location handling. If
there is a clean patch to move to Lexing.position, feel free to propose it.
If this requires invasive changes with a larger chance of regressions, it's
maybe not worth it.

(Note that there seem to be some uses of Lexing.position already in the
file, but only in some cases. I don't know the detail and you may have some
"git log" mining to understand them.)
