This reverts commit 88b5578a57 because of the
following issues:
1) If $OPENSSL_X509_CERT_FILE is set in the current shell environment, then
its value will overwrite any settings the user may have configured in
http.sslCAInfo via git-config(1). If you are unaware of the wrapper, then
this behavior is totally unexpected as $OPENSSL_X509_CERT_FILE is not
supposed to have an effect on Git.
2) The patch makes it impossible for Git users to use the $GIT_SSL_CAINFO
environment variable as documented in git-config(1), because anything set
there will be overwritten with the value of $OPENSSL_X509_CERT_FILE (which
might be empty).
3) The patch breaks other builds of packages that depend on Git, i.e.
<http://hydra.nixos.org/build/11995872/nixlog/1/raw>.
