[PATCH 1/2] [submodule] handle multibyte characters in name

[Fredrik Gustafsson <iveqy@iveqy.com>]

Bugg reported here:
http://thread.gmane.org/gmane.comp.version-control.git/218922/focus=226791

Note that newline (\n) is still not supported and will not be until the
sh-script is replaced by something in an other language. This however
let us to use mostly all other strange characters.
