ctrl-c doesn't always work when entering text in ghci

[judahj]

With ghci-7.5.20120519 (on Mac and probably also Linux): type some text, then press ctrl-c. Then type more text, and press ctrl-c again. The first time you press ctrl-c, it starts a new line. But the second time you press ctrl-c, nothing happens. (Actually running code from within ghci resets this process.)

This is a regression from the behavior of ghci-7.4.1, where every time you press ctrl-C it caused a new line to be printed.

From my initial investigation, I think this was caused by ghc commit 206c8fc3ebd64c40ae09742fdea09ffd0f915d5c, which was used to fix #2786.
