The merge of this topic into jch (at 766f92478b0) causes the test suite
to fail when compiled with ASan/UBSan. The simplest reproduction I could
come up with is:
$ make SANITIZE=address,undefined BLK_SHA1=1 &&
GIT_DIR=nope ./git shortlog </dev/null >/dev/null
repository.c:69:31: runtime error: index 1869098813 out of bounds for type
'git_hash_algo [1]'
Note that the series is fine by itself, it's only the merge which fails.
Which implies to me it's some funny interaction with bc/hash-algo (which
introduces the hash_algo concept). But I didn't dig further.
