This trick was performed via $ (cd t && sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \ -e 's/Master/Main/g' -- t6[4-9]*.sh) This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main` for those tests.

Actual similarity indices are parsed from diff output. We rely on the fact that
|
|
they are rounded down (see, e.g., Documentation/diff-generate-patch.txt, which

mentions this in a different context).
