generate-cmdlist.sh: replace for loop by printf's auto-repeat feature

j6t · gitster · commit 66d55b990ea0 · 2021-11-05T12:01:13.000-07:00
This is just a small code reduction. There is a small probability that
the new code breaks when the category list is empty. But that would be
noticed during the compile step.
