Subject: [PATCH] rc tools git: fix regression hiding blame in large files

Sorry I did not test my earlier patch in production.  It passes
blame flags via the environment.  On a 5000 line file this results in
"execve failed: Argument list too long" errors.

Use a different way of checking whether blame info is shown.
