Subject: [PATCH] Update updater.sh

> If you do not give `read` any arguments to use to hold the input (relying on the default variable `REPLY`), no whitespace is stripped and you can omit the modification to `IFS`. That is, `while read -r; do printf '%s\n' "$REPLY"; done < "$file"`

from a comment by chepner in response to the answer at https://stackoverflow.com/a/29689199

thanks chepner
