All changes in this patch were performed automatically with `shfmt` with
configuration flags specified in `.pre-commit-config.yaml`.
In addition to fixing whitespace the roundtrip through shfmt's AST also
transforms command substitutions
`cmd`
# becomes
$(cmd)
and some redirects
>&2 echo "msg"
# becomes
echo >&2 "msg"
For trace files that require authentication to download, hide
part of the URL in output messages. This avoids leaking potentially
sensitive info when running tests using a continuous integration
service.
The traces for external test-suites are no longer kept inside the
repositories themselves but downloaded separately via curl. This is
because git is pretty bad at dealing with large files.
See the README for more information.
