I removed the comment because it is simply incorrect. If there should be
a comment, it should descripe why the on-disk offset in the directory is
not, but the added comment didn't do that. Arguments against using it
that way is the complication of code [for a secondary filesystem] and
the possible security issues coming from it.
The wraparound test was not removed, but coded explicitly. Checking for
two types having identical values is a bad thing, because it can
surprising results when both types have the same width and different
signedness.
