Hi,
I just wonder if the aim was to put every part of the list to their own lines
111.
222.
333.
44.
555
If it was, then the "add wrap character with SQL" is fine. If the aim was to keep the label on as few lines as possible and space admitting have
111.222.333.44.555 or
111.222.333.
44.555
then I fear that no workaround is usable and the real solution would be to change the code to support option "don't eat wrap characters"

Great work Benjamin! (I was looking at that page but didn't think of using substring) Benjamin's solution works great (assuming your data is always in 111.222.333.44.555 Here is a working example:
map output: http://pasteboard.co/25N6NcOV.png
layer snippet:
LAYER

CONNECTION "cities.shp"
DATA "SELECT
CONCAT(SUBSTR(PARCEL,1,3),'.+',SUBSTR(PARCEL,5,3),'.+',SUBSTR(PARCEL,9,3),'.+',SUBSTR(PARCEL,13,2),'.+',SUBSTR(PARCEL,16,4))
AS parcel_wrap from cities"
LabelItem "parcel_wrap"
CLASS
NAME "mycities"
LABEL

PARTIALS FALSE
OUTLINECOLOR 255 255 255
WRAP "+"
