config script fails to read previously set locales

[ArmouredHeart]

To replicate:

1. run ./config
2. set locales to en_CA.utf8 and C.utf8
3. save and exit
4. run ./config again

Thanks for the report, the problem is now fixed.
I'm sorry for taking so long to respond, I had some very busy past months.

In case you are interested in the actual issue: bash array expansion like ${arr[*]} is dependent on $IFS to determine the delimiter that is inserted between elements. I had expected it to always be space delimited, but coincidentally the IFS had been modified and set to \n for some other parsing logic in the relevant function, which caused the problem.
