Reduce chance of mistakes with unsafe_shell check during refactor

Browse Source 
Code like this:

if cond1 and cond2:
    pass
elif cond1:
    pass

Has a hidden dependency on the order that the conditions are checked.
This makes them fragile and subject to breakage during refactors.
Rewrite the code like this:

if cond1:
    if cond2:
        pass
    else:
        pass

The nested structure makes the ordering explicit and less likely for
someone to break the code when they refactor.
