Nicely done. I am not sure if you need to say the "update the
conditional...", which is a logical consequence of such a conversion
and goes without saying, though.

This part may overlap with other topics in flight, but I expect the
conflict resolution would be trivial.

Let's just say
if (!*slash)
instead; it is more idiomatic (I won't repeat this for other hunks).

After this "if (!*slash)", we compute "namelen = slash-path".
Perhaps we can lose this assignment and the other one by hoisting it
up before "if (!*slash)"?

Huh? "The byte pointed at by 'slash' is NUL, or it is NUL"???
Other than that, looks good to me.
Thanks.
