#56 Negative indexing in MultiColumnList.InsertItems

[Anonymous]

A typo in multicolumnlist.py prevents
MultiColumnList.InsertItems from disallowing improper
negative indexing:

# Allow negative indexing to mean from the end of the list
if position < 0:
position = numitems + position
# But only allow from the start of the list on
if position < 0:
postiion = 0 <-- *** typo ***
