It seems you missed it but we already have this code tested "in the
wild", i.e. the "new" code here is really just copy/pasting test setup
from above.
So maybe we want to change (and you have some good suggestions here),
but it's already shown itself to be portable enough. We've had this
"sed" command since v1.7.2, or 567102819ac (Add test for correct
coloring of git log --decoration, 2010-06-29).
