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.)
