Fix for opening files that don't exist

Cautious-file uses canonicalizePath itself. If you try to save file that doesn't exist, you'll get the same error (on GHC >= 7.0.1).

Hmm, alright. I think I'll pull this, but file a bug with cautious-file. If/when it's fixed, we can uncomment it.

(I think the package could also support Windows out-of-the-box now with some *.cabal work, which would mean we could get rid of the preprocessor flags altogether.)

If you want to jump on this, Hackage lists Robin Green as the maintainer of that package; it'll be a few days before I can email about this bug, but go ahead if you want.

[vasil-nesterov]

Ok, I've informed Robin Green about problems with cautious-file.

[jeffwheeler]

Looks great now! Thanks for pinging Robin, also.

I'm ready to pull the commits, but why did you delete .gitignore?

[vasil-nesterov]

Hm, I haven't thought about problems it might cause. If it makes merging troublesome, I'll put it back.

[jeffwheeler]

Applied; thanks!

(Although I kinda made a mess of applying it . . . pushed it to my own github copy first, then pulled the commits to the main repo from there rather than doing a proper merge. Oh well. That's what I get for being a git newbie.)
