Sorry, but what's PNPM?

Style. Lose semicolon, have "do" on the next line on its own,
aligned with "for". Tip: you shouldn't need any semicolon other
than the doubled ones in case/esac in your shell script.

Hmph, after seeing the discussion thread of v1, I was expecting to
see a helper in Perl that cd's down and then comes back up while
removing what is in its directory (and I expected something similar
for creation side we saw above).
