The minor patch below clarifies what the computation is about and
removes the assumption that point-min == 1, while arguably
making the the code ever so slightly more efficient.

Subject: [PATCH] (org-src-font-lock-fontify-block): Clarify offset computation

* lisp/org-src.el (org-src-font-lock-fontify-block): Improve the translation
of local positions into org-buffer positions, and get rid of
assumption about the value of `point-min` while we're at it.
