Signature
(-concat &rest SEQUENCES)
Documentation
Concatenate all SEQUENCES and make the result a list.
The result is a list whose elements are the elements of all the arguments. Each argument may be a list, vector or string.
All arguments except the last argument are copied. The last argument is just used as the tail of the new list. If the last argument is not a list, this results in a dotted list.
As an exception, if all the arguments except the last are nil, and the last argument is not a list, the return value is that last argument unaltered, not a list.
