Show variables read-only info

[kidonng]

Fish recently added read-only info to set --show in fish-shell/fish-shell@3db7823, however the way it displays is not covered by current regexes. I have some solutions in mind but they are not ideal, so I'm opening this discussion to see if someone have a better idea.

Can you provide an example output that is problematic?

I'm not testing the master branch fish but you can look at the linked commit, in tests/checks/set.fish, the #CHECK comments are checking for output, so the expected output will be something like:

$status: set in global scope, unexported, with 1 elements
Variable is read-only
$status[1]: |0|

Interesting. I think we can either

1. Open an issue fish-shell to add $status to the "Variable is read-only line"
2. Just filter it out, maybe users don't care to have that info
