The following is rough, but could give you an idea for one possible
approach...
:let dict = {}|let arr = []|g/^./exe "if has_key(dict, getline('.'))|
call add(arr, line('.'))|endif|let dict[getline('.')] = 1"
After executing the command above, the line numbers of redundant lines
should be in array "arr".
Hope it helps...
