[PATCH] config: add quoting to fix IFS bug

[Jameson Graef Rollins]

Without proper quoting the DEFAULT_IFS was getting set incorrectly,
which was causing problems with the storage of some variables later in
the script.  Quoting fixes the problem.

Thanks to Tomi for the inspiration for this fix.  I don't know how I
missed such a simple solution initially.
