fmt: improved version using less memory

functional identical, but uses different data structure.
instead of reading all words into memory, we read and
tokenize on demand keeping a simple linked list of words
to conume by further calls of getword(). once the list
is empty we read the next line, tokenize it and fill the
list up again. so we only need as mutch memory to hold
all the words of the longest line.
