Bug in %read-delimited! ?

["Brian F. Dennis" <xjam@cs.berkeley.edu>]

There's a clause in %read-delimited! that reads:

...
                    ((>= i end)                 ; Filled the buffer.
                     (if gobble? (read-char port))
                     (values #f (- i start)))
...

I don't believe you actually want to do the gobble in that clause because
your only at the end of the buffer. 

This bug means that the replacement read-line in scsh misses the 80th
character of each line if there is one.
