Build error with filenames containing unicode characters

[bpabel]

I'm trying to build a project that has files that contain unicode characters in their filename. I can build the wheel successfully, but building the sdist results in the following error.

$ flit build
Found 6 files tracked in git                                                                                                                                   I-flit.sdist

Thanks. It looks like git ls-files quotes the filename for us when it's called here:

https://github.com/takluyver/flit/blob/cfd71d81be95300266c6e989cf2d1bf57aa637fc/flit/vcs/git.py#L6-L9

I see it has a -z option to give the raw filenames delimited by null bytes. That's probably what we need.

@takluyver You were exactly right, thanks! Changing that fixed the issue (see #346 )
