That is because of this:

    $ (sh t7900-maintenance.sh 2>&1; echo $?) | tail -5
    ok 25 - register preserves existing strategy
    t7900-maintenance.sh: line 444: test_execpt_success: command not found
    # passed all 25 test(s)
    1..25
    0

The story is the same with prove.

    $ prove t7900-maintenance-sh
    t7900-maintenance.sh .. 24/? t7900-maintenance.sh: line 444: test_execpt_success: command not found
    t7900-maintenance.sh .. ok
    All tests successful.
    Files=1, Tests=25,  2 wallclock secs ( 0.02 usr  0.01 sys +  0.97 cusr  0.97 csys =  1.97 CPU)
    Result: PASS

Since this typo appeared immediately before test_done, we _could_
improve test_done to pay attention to $? when it starts (and in a
similar fashion, we _could_ also check $? at the beginning of the
test_expect_* for the previous step), but I do not think that is a
good approach that would scale well.  There are legitimate reasons
we have to write things other than test_expect_* at the top level
of the script (e.g. test helper function may have to be defined to
be shared amongst the test pieces in the same script).

I wonder if it is a good direction to go to run the tests with the
"set -e" option on, and accept its peculiarities.
