Attempting to workaround the issue proved futile. Using
internal Deflater-specific keys to prevent deflating in
GitHTTPBackend and Qspawn did not solve the problem:
$env->{"plack.skip-deflater"} = 1;
$env->{"psgix.no-compress"} = 1;
Nor did forcing an invalid encoding via "git fetch":
git -c http.extraheader=Accept-Encoding:gzap fetch
So this appears to be a problem with Plack::Util::response_cb
somewhere.
