[Toybox] [PATCH] cp: fix -D (--parents)

[Rob Landley]

Sorry, flew back from Japan to Austin on tuesday am I'm still deep in the grip
of jetlag, and buried about 5 todo items deep.

Lemme try to get the patch fuzz fix committed, and then track down the use after
free in config2help, and then I can do this before getting back to the mkroot
and toolchain stuff from https://landley.net/notes.html#18-02-2020 and then I'd
think maybe I could get back to finishing the toysh variable expansion plumbing
(where did I leave off... I need to unify the quote traversal logic so I don't
have to teach two different places that $((echo hello) | wc) parses as $( ( ) )
and not $(( )), but I got distracted from that by implementing the "!" command
which is like ":" but doesn't have a base command name I can feed to NEWTOY()
and I can't do an OLDTOY() without a NEWTOY(), so there's design work...)

But it'll be monday by then and I should do $DAYJOB stuff again.

(While I'm at it, I need to figure out why ifconfig in mkroot called from toysh
is saying "ifconfig: bad argument '.0.2.15'" (is that a toysh bug or an ifconfig
bug), oh and I want to add xattr support to tar before the next release, which
is a month overdue. And I finished setting up the local debug environment for
the README->README.md conversion but didn't _do_ the conversion because I
haven't learned the new markup yet. Oh and md5sum is throwing a broken warning
with gcc 9 I can't typecast away so I need to turn a memset() into a for loop so
gcc can't understand what I'm doing enough to complain about it (I'm blanking
the second half of a struct after calculating the hash, I sorted the members so
this does what I want and yes it's intentional)), I wanted to make mount use
block2mtd with jffs2.img, swapon -a, test should learn the ~= regex match, the
can of worms that is faq.html...)

(P.S. I'm sorry I haven't reproduced
