Yeah, you're completely right, this was a misunderstanding on my part;
my fix just happened to also work so I made some incorrect assumptions.
After some further testing, this seems to happen for packages for which
the doc file is in the base directory of the package (which causes
'file-name-directory' to return nil as the doc file name is relative to
the package dir).
I attached an updated patch.

1. $ emacs -Q
2. M-x package-vc-install RET eat RET
3. A few seconds later,
"package-vc--unpack-1: Wrong type argument: stringp, nil"

I haven't tested it, but I don't see a reason it wont.
