Hmm, I still don’t understand this.  Do you mean that there is
some setup that needs to be run before these commands, and so
the patch fails if that change is not included?

Or is it a matter of "while at it, fix this other problem
I noticed" (which would be fine, but it is clearer to
present it as such if so)?

Tip for the future: if you use 'straight quotes', then readers
can avoid carefully scanning through for $ and similar oddities
(and the test script presented with the "expecting success:"
prompt will use the friendlier $tree instead of 76c98ds89).

The patch looks good; my only remaining concern is the log
message as mentioned above.

Thanks,
Jonathan
