As you talk about GIT_ATTR_SOURCE, I wonder if this variable should
also be documented in the "Environment Variables" section of this
Documentation/git.txt doc.

To be similar with the definitions that are just above, I think it
actually should be:
#define GIT_ATTR_SOURCE_ENVIRONMENT "GIT_ATTR_SOURCE"

The example I sent was about '--super-prefix' so it made sense to say
"no prefix given", but here it makes more sense to say something like
"no attribute source given for --attr-source".
