Thanks for the review. I thought of doing that, but thought that it
might add some latent complications - in particular, someone inspecting
the environment variables of this running process might see some
environment variables that they didn't set. But I'm OK either way.

Data can be turned on using GIT_TRACE_CURL=1 and refraining from setting
GIT_TRACE_CURL_NO_DATA. What knobs were you thinking of?
