One nice thing tbdiff did was to right align patch numbers (which also
helped align other columns in the output). So, for example when there
are more than 9 patches I would see output like:
...
8: a980de43fd = 8: 362ab315ac directory rename detection: testcases
exploring possibly suboptimal merges
9: 3633e79ed9 = 9: 792e1371d9 directory rename detection:
miscellaneous testcases to complete coverage
10: e10d07ef40 = 10: a0b0a15103 directory rename detection: tests for
handling overwriting untracked files
11: f6d84b503e = 11: a7a436042a directory rename detection: tests for
handling overwriting dirty files
...
whereas branch-diff here is instead giving output of the form
...
8: a980de43fd = 8: 362ab315ac directory rename detection: testcases
exploring possibly suboptimal merges
9: 3633e79ed9 = 9: 792e1371d9 directory rename detection:
miscellaneous testcases to complete coverage
10: e10d07ef40 = 10: a0b0a15103 directory rename detection: tests
for handling overwriting untracked files
11: f6d84b503e = 11: a7a436042a directory rename detection: tests
for handling overwriting dirty files
...
Not a critical difference, but it'd be nice to match tbdiff here all the same.

Same comment on these last two strbuf_addf's about alignment.
