It was bothering me a lot that I abused small integer values casted to (void *) to represent non string values in gitattributes. This corrects it by making the type of attribute values (const char *), and using the address of a few statically allocated character buffer to denote true/false. Unset attributes are represented as having NULLs as their values. Added in-header documentation to explain how git_checkattr() routine should be called. Signed-off-by: Junio C Hamano <junkio@cox.net>
