"The default" should not be hardcoded in the tool.

By setting the encoding to "system", "the default" is taken from whatever
the system's current locale is. If you are on modern Linux, your locale is
most likely set to UTF8, and everything is fine; you won't observe a
change in behavior.

But if you are on a system whose locale was not set to UTF8, then you very
likely did *not* produce UTF8 data, and the display in git-gui was screwed
because it assumed UTF8. With this change it uses the system's encoding,
and it is an improvement.

How can you know? For example, I've to work with systems that use "legacy
encodings", and I can't use UTF8 in my data. Hence, the default of UTF8
was not exactly useful. With this patch series there's now a mechanism
that allows me to state the encoding per file, and all platforms should be
able to show the data in the correct way.
