Infinite loop with File.Readdir()

[lmas]

Edit: cleaned up the whole issue...

The documentation for os.File.Readdir(n) states that when n > 0, Readdir() must return a io.EOF at the end of the directory.
rice.File.Readdir() doesn't comform to this behavior, for appended files and dirs, and so we will enter an infinite loop in https://golang.org/src/net/http/fs.go#L70 when we try to serve appended files with http.FileServer and rice.box.HTTPBox().

I'm afraid that rice.File.Readdir() needs to be rewritten so it instead will work over multiple calls (for example: first call returns all files/dirs in current dir, second call returns io.EOF to end the loop). But that means it needs to save some kind of state and shit, so it would be a pretty big change...
Edit: Nvm, I finally noticed you already got it figured out, for embedded files at least.

Duplicated by #108. Work is being done in that issue to solve this bug. Thanks for reporting!
