butlast -- Operation, one input. Abbreviation: bl
The input may be any non-empty Logo object. If the input is a list,
the output is a list equal to the input list with the last member re-
moved. (If the input list has only one member, the output is the emp-
ty list, a list of zero members.) If the input is a word, the output
is a word equal to the input word with the last letter removed. (If
the input is a single-letter word, the output is the empty word.) If
the input is empty, an error results.
