                          shellcheck generated the following warning

    SC2155: Declare and assign separately to avoid masking return
    values

For this line of code

    local key_value=$(echo "$current_line" | mawk '/.+=.+/ {print $1 }')

What does "masking return values" mean, and how does it pertain to the aforementioned warning?
