Aha!
I am running an agent, and GPG_AGENT_INFO is set, but gpg.conf did not
include use-agent. I was confused because other applications (other than
the gpg command) were using the agent by default.
Setting use-agent means that obnam asks for my passphrase correctly.
(It occurs to me that it might make sense for obnam to remember the
symmetric key on the run that it generates it, to avoid asking the user
for the passphrase to decrypt it. On the other hand, forcing the user to
enter their passphrase on the first run might help the user avoid making
backups that they can't access.)
However, now I get a different error.
