Update ls.tsx

Browse Source 
`args[numArgs - 1]` is the last argument in the list, so correct usage was being flagged as incorrect, and incorrect usage wasn't working anyway because the filter was `"undefined"`.

Additionally, the function seemed confused as to whether or not `ls` counted as an argument (AFAICT, it isn't).

Fixes #1994.
