Add a way to approve specific shell commands

in v1.7.3 - Q asks me whether I 'trust' all shell commands. I don't. A 'shell command' is way too broad for me. But I'm ok trusting specific ones, eg all non-destructive ones like cat, sort, cut, uniq, find, ls, grep, cat, less, sed, pwd, ...

also _some_ git commands like 'git add', 'git diff', 'git status',

This feature request is to enable me to specify and review commands that i trust. I think some of that already exists - Q does not ask when using `ls` for example. I would be nice to be able to see those trusted commands and edit the list.
