Even though I do not think I would reject a patch to add this entire
file if the variable were named git_attr_nr from day one (read: the
result of the patch is not wrong per-se), I am not sure if the
variable deserves "git_" prefix that makes it look as if it may need
to be protected from global namespace contamination, given that this
is a file-scope static.
It might make a lot more sense not to do this rename, but change the
first parameter of macroexpand_one() from attr_nr to something more
appropriate, like "struct git_attr *attr"?
