I guess if you do set the locale it will be ok?

I think we can do that (there may be a bug for it).  For filenames it
is harder to override what Python thinks the encoding ought to be.

vim apparently also has some issues with non-locale-encoded filenames
<http://comments.gmane.org/gmane.editors.vim.devel/28508>.

There are more dimensions on which people may want to vary (or have to
vary) than Unix's concept of locale can really capture: you might want
to write your commit message in utf-8, have filenames in euc, and have
the text interface just run in C...  But, even beyond just needing to
implement those variations, we are a bit constrained what Python will
actually let us implement.

Anyhow, on the specific thing of this patch, of defaulting to utf-8,
if gz feels we should leave it in, that's ok with me.  It should only
be active in fairly edge cases of having non-ascii names and an
explicitly or implicitly ascii locale.
