Surely you meant "succeed" and "fail" the other way around :)

Clever.
If I do a
- error 'bug in test script: missing "&&" in test commands'
+ say_color error 'error: bug in test script: missing "&&" in
test commands'
to avoid erroring out and skipping the rest of the test script on the
first broken command chain, then we can see that we have a lot of
broken command chains in the test suite:
$ for t in t[0-9][0-9][0-9][0-9]*.sh ; do ./$t ; done |grep -c
'^error:.*missing "&&" in test commands$'
345
After a cursory look most of them seem to be the simple "missing &&"
type, but there are some funny ones, too.
