Yes, that's a good point. And one I should have known from
reading it here more than once. Thanks to both of you.

Heh, I had written a similar reply already, but then I got
side-tracked for a bit...
I think the grep needs to be negated, e.g.:
! grep ^cherry$ actual
Otherwise it succeeds without the fix, as cherry-pick is
expected to be in the --list-cmds output. (If we remove
the 'expected' file, it might also make sense to rename
'actual' to 'out' perhaps.)

True. With the simplified test, that's easy enough to add
and makes the test description more accurate and the test
more thorough. I'll adjust it like so when I re-send:
test_expect_failure 'completion.commands removes multiple commands' '
test_config completion.commands "-cherry -mergetool" &&
git --list-cmds=list-mainporcelain,list-complete,config >out &&
! grep -E "^(cherry|mergetool)$" out
(Using test_config depends on setup_git_directory_gently() in
list_cmds(), which Jeff suggested elsewhere in the thread.)
Thanks!
