[PATCH v5 0/4] support uTF-8 in alias names

Heya!

This series enables UTF-8 and special characters in Git alias names by using config subsection syntax: [alias "name"] command = value.

I have since last time:
* Changed "native speakers" to "languages outside English range" (thanks Richard!)
* Fixed shell completion in zsh
* Improved docs slightly with feedback from Junio. Also changed out one of the examples with one with spaces to demonstrate that feature.

Thanks for your time.
