parameter is used to retrieve more input characters. GET should
set its parameter to point to a buffer, and return the length of
the buffer; it should return 0 at end of file. The scrubbed output
characters are put into the buffer starting at TOSTART; the TOSTART
buffer is TOLEN bytes in length. The function returns the number
of scrubbed characters put into TOSTART. This will be TOLEN unless
end of file was seen. This function is arranged as a state
machine, and saves its state so that it may return at any point.
This is the way the old code used to work. */
