Re: [PATCH 2/2] tests: make test_must_fail fail on missing commands

The point of it is to run a command that produces failure. A
missing command is more likely an error in the test script

Makes sense.  Here's the corresponding change for test_might_fail.

Subject: tests: make test_might_fail fail on missing commands

Detect and report hard-to-notice spelling mistakes like

 test_might_fail "git config --unset whatever"

(the extra quotes prevent the shell from running git as intended;
instead, the shell looks for a "git config --unset whatever" file).
