t64*: preemptively adjust alignment to prepare for `master` -> `main`
We are in the process of renaming the default branch name to `main`,
which is two characters shorter than `master`. Therefore, some lines
need to be adjusted in t6416, t6422 and t6427 that want to align text
involving the default branch name.
