Comment (by tim):

 Replying to [comment:4 judah]:
 > Just to clarify: what happens when you type :!stty -a from inside ghci
 immediately after entering ghci?

 Still the same output as what I pasted.

 > I suspect this is a problem with libedit, since HEAD replaced readline
 with it it between 6.8 and 6.10.  Do you know of any other programs on
 your machine that use libedit and whether they have the same issue?
 Otherwise, would it be possible for you to compile the following C program
 (with {{{gcc -ledit}}}) and check its behavior inside the xterm?

 Done (I had to install libedit-dev first, but I don't think that had any
 other effects); your test program works fine (backspace, delete, Ctrl-U)
 work, when it's run in an xterm, but still the same problem with ghci.
