I find it useful to add the broken test in a separate patch, because it is then easy to cherry pick that patch to other versions of Git to discover which ones are also affected by the problem. If the addition of the test is combined with the fix, then the patch would more often fail to apply to other versions due to conflicts at the locations of the fix, and even if it applied, you wouldn't learn whether that version of git was broken but the breakage was fixed by the same fix, or whether it wasn't broken in the first place and the fix was unnecessary.
