Usually we would prefer environment variables to config. So that:

  $ git config http.proxy foo
  $ HTTP_PROXY=bar git fetch

would use "bar" as the proxy, not "foo". But your code above would
prefer "foo", right?

Apparently I'm the author of the http.proxy feature, though I barely
remember what problem I was actually solving at the time.  At the
time I justified it on the grounds that a user might want to use a
different proxy for git and/or a particular remote.  The "http_proxy"
environment variable is likely to be a global system default, or
perhaps a desktop setting, and therefore I'd say probably less and
not more specific than a git configuration variable.

Good point. We sometimes follow this order:

  1. git-specific environment variables (i.e., $GIT_HTTP_PROXY, if
     it existed)
  2. git config files (i.e., http.proxy)
  3. generic system environment (i.e., $http_proxy).

So thinking about it that way, the original patch makes more sense.
