It is used to avoid "var may be used uninitialized" warnings for some
compilers. Officially (according to the C standard), it is undefined
behavior. But I've observed considerable resistance by Junio to fix this
properly. Therefore, unless you can show that your compiler generates
unusable code you better live with the "self-initialization" warnings.
