oliver mentioned in w/54389 that the check sums are meant for integrity
verification, not security. but i'd be ok with this personally

i don't have any experience pgp-signing e-mails myself, so not sure how
much friction it would add, but maybe

as part of the release process the artefacts are uploaded to these two
locations:

  https://sourceforge.net/projects/zsh/files/
  https://zsh.org/pub/

these are completely independent services, so if you're worried you
could cross-reference them. i guess a compromise of both is possible via
a dev's ssh key/agent though

sf also independently calculates its own check sums (click the little
'info' icon). but it doesn't seem to do sha-256
