`status` built its job list with `for n in $names`, which word-splits AND globs. The
second half is the bug: a job named `x*` was expanded against the caller's working
directory, so the report described unrelated files there as jobs and never mentioned
the one that ran — on a harness whose whole purpose is a report you can trust after
the session that started the job is gone. Splitting stays (several names in one
argument is the documented call shape); expansion goes.
`tail` was honest-by-accident in the wrong direction: with no jobs it handed a
literal `$JOBS/*.out` to tail, which reports a missing *file* — indistinguishable
from a broken tool — and a missing name produced tail's errno rather than "no job
called that". Both now say what is missing and exit 1.
Red first: the name test reads the report from a directory containing an unrelated
file, so the old glob is visible as a phantom job; both new tests fail against the
previous code and pass against this one.
