Fixed as:

+   It is assumed that memory can be accessed from:
+     PTR + (OFFSET_BITS / TARGET_CHAR_BIT)
+   to:
+     PTR + ((OFFSET_BITS + LENGTH_BITS + TARGET_CHAR_BIT - 1)
+            / TARGET_CHAR_BIT)  */

Tightened up on this throughout.

Fixed.

I've pushed a version with those minor fixes.

Thanks for all your reviews.
