Fix cabal repl handling of Ctrl-C

[dagit]

The code here does fix #1448, but since it "borrows" code directly from the process package this may not be the best way to fix it. See for example, http://ghc.haskell.org/trac/ghc/ticket/8419.

Please let me know if I need to change anything so that we can squash this C-c handling bug :)

I think that this a fine workaround, but it'd be nice to fix the issue in process itself.

We should do both, fix process and merge this workaround. @23Skidoo if the code looks fine to you feel free to merge.

Awesome. Any chance to get this in a bug fix release on Hackage?

That's up to @tibbe.

@dagit Apparently you didn't test your code on Windows. Fixed in 940079c. @tibbe, if you decide to backport this to 1.18, please also include my Windows fix.

[dagit]

@23Skidoo You're right. I didn't test on windows. Sorry about that. Things got merged a) quicker than I had time to update them b) quicker than I expected :)

I was hoping to switch to bracket here and in process this weekend, but I was busy with other stuff. I'll try to get that patch submitted this week, before I get bogged down in work + courseras.

Thanks for merging this and fixing up the windows stuff!

Nice. Improvements welcome, of course.
