Wish: non-UTF-8 source files

[the-Arioch]

For git itself the charset of committed files does not matter, it more or less works with byte streams.

However, it is important for GUI tools like diff/merge.

While many source files of today are encoded in UTF-8 it is not always so, especially with legacy projects. Especially comments there, user UI texts, etc.

Feature requests: for repositories (and maybe also for folders and even particular files) provide user setting of source files charset, so DIFF would be seen in human-readable way.
