Re: [RFC/PATCH 1/2] Add a useful return value to git-check-attr

git-check-attr previously always returned success.  With this patch it
returns success when the requested attribute is found for all supplied
paths.

This lets you check in a script whether a file has an attribute:

 $ git-check-attr attribute -- file && echo "file has attribute"

I wrote check-attr primarily to have a quick way to make sure
the attribute stack is working properly, but I agree making
gitattributes available to scripts is important to make it
useful in general.

And your patch was a step in the right direction based on my
previous patch.

But sorry, you were shooting at a target that is still moving
too fast, and you missed.  It's not your fault, as even I did
not know where it was heading to, but my plan has been to have
the scripts parse the text output, as we would need more than
true/false values, as I did in the four patch series I sent out
tonight.
