This sounds like a bug:  either editline or ghci assumes that when it  
successfully reads data which lacks a line terminator than it has seen  
an EOF, so inserts a ^D.  But if it received the data at the maximum  
tty buffer size (255) then there is no trigger character.

(This is easy enough to work around:  special-case reads of length  
255.  But in reality, this means something is Doing It Wrong.)
