Just want to note that if you are retrieving sub-strings of
length zero, this function breaks in the base case (the
source being an empty string):

    substr('123',0,0) returns string(0) ""
    substr('12',0,0) returns string(0) ""
    substr('1',0,0) returns string(0) ""

but

    substr('',0,0) returns bool(false)

Although this is the documented behavior, I would consider
it unexpected in many circumstances.
