It will be present in any likely future reimplementation, and its availability simplifies other code. Signed-off-by: Michael Haggerty <redacted> --- struct git_attr is an opaque structure containing, among other things, the name of the attribute that it represents. This patch adds a function git_attr_name(struct git_attr *) that allows the name to be read from the structure. This functionality will be convenient for later patches. This seems harmless to me. It is hardly conceivable that the implementation will change so dramatically that it becomes impossible to derive the attribute name from the git_attr. Please check that the name that I chose for this function conforms to git conventions.
