If it was buggy, the care given to it probably was insufficient, not
overkill ;-)

As long as we know there won't be an overflow, and our compilers
won't complain about possible overflow, simpler code that is easier
to reason about is better.  I tend to think that Peff's
"consistently count based on offsets, instead of pointer arithmetic
that you can easily get wrong" would give us an easier-to-read
result in this case.

Thanks for simplifying the original "overkill" version.  Except for
the bug resulting from misunderstanding of strlcpy() return value,
the version I saw was a quite pleasant read.
