Subject: [PATCH] Correctly report errors happening in functions

`trap ... ERR` does not automatically propagate to functions. Therefore,
Our fancy error-reporting mechanism did not catch errors happening in
functions; and we do most of the actual work in functions. The solution
is to `set -E` or `set -o errtrace`.
