This CL allows for searching sections by their permissions. For instance, you could search for all rwx sections by typing vmmap rwx.

could be useful. We might want to add this as a flag argument though, e.g. vmmap --perms rwx.

Maybe we could even support a 'don't care' e.g. r?? vs r--, the former allowing rw-, r-x, etc. Maybe a good idea for a followup.

I think if we put this behind a flag, we should do it for the other filters too?
Like --addr for searching addresses and --name for searching with the name?
I think the goal here is to make it easily useable, without too much friction (I guess that's why there is no --addr/--name?) so in order to stay consistent I think its better to keep it this way

But I think the idea of ? is great I'll do that :)
