t4211: fix broken test when one -L range is subset of another t4211 attempts to test multiple git-log -L ranges where one range is a superset of the other, and falsely succeeds because its "expected" output is incorrect. Overlapping -L ranges handed to git-log are coalesced by line-log.c:sort_and_merge_range_set() into a set of non-overlapping, disjoint ranges. When one range is a subset of another, sort_and_merge_range_set() should coalesce both ranges to the superset range, but instead the coalesced range often is incorrectly truncated to the end of the subset range. For example, ranges 2-8 and 3-4 are coalesced incorrectly to 2-4. One can observe this incorrect behavior with git-log -L using the test repository created by t4211. The superset/subset ranges t4211 employs are 4-$ and 8-12 (where $ represents end-of-file). The coalesced range should be 4-$. Manually invoking git-log with the same ranges the test employs, we see: % git log -L 4:a.c simple | awk '/^commit [0-9a-f]{40}/ { print substr($2,1,7) }' 4659538 100b61a 39b6eb2 a6eb826 f04fb20 de4c48a % git log -L 8,12:a.c simple | awk ... f04fb20 de4c48a % git log -L 4:a.c -L 8,12:a.c simple | awk ... a6eb826 f04fb20 de4c48a This last output is incorrect. 8-12 is a subset of 4-$, hence the output of the coalesced range should be the same as the 4-$ output shown first. In fact, the above incorrect output is the truncated bogus range 4-12: % git log -L 4,12:a.c simple | awk ... a6eb826 f04fb20 de4c48a Fix the test to correctly fail in the presence of the sort_and_merge_range_set() coalescing bug.
