New issue 295 by DexterPu: Strange overlay behavior (Vty frontend on OS X)
http://code.google.com/p/yi-editor/issues/detail?id=295

What steps will reproduce the problem?
1. launch yi with emacs keymap
2. open a directory with Dired mode (C-x d)
3. (notice the color of the first line) refresh the dired buffer (g)

What is the expected output? What do you see instead?
I'm using black background.
The color of the first line of Dired buffer should always be grey (the
style used is `headStyle = const (withFg grey)' in diredRefresh), but run
diredRefresh again will change it to the color of the last entry in the
buffer (either blue or white).

I noticed that diredRefresh did not clean previous overlays, and I failed
to find such a overlay reset function either. I had a peek at the overlay
code, but cannot figure out what's wrong.

Please provide relevant version information:

What version of Yi are you using?
fresh darcs version

What version of GHC?
6.10.4

What version of Cabal?
1.6.0.3

What operating system/version?
Mac OS X Leopord 10.5.8

If you generated it (--debug) please provide your .yi.dbg file

Please provide any additional information below.

This can be observed both on iTerm.app and Terminal.app
