I fixed this because it was being an issue for debugging CI failures.

We try to print as much information as possible, just with a slightly less verbose command description in non-verbose mode. The code is now more unified and hopefully simpler to understand.

I also fixed the format_short_cmd logic, it was a bit weird after some recent refactors.

Fixes: #145002
