Documentation: Describe how to deal with snooping https proxies

Disabling SSL verification is far from optimal, but depending on the
circumstances may be the most practical way, so describe how to do
that instead of leaving users confused.

It's also not _that_ bad because git's hashing scheme should uncover
most attempts to tamper with code, either when checking signed tags
or when people push (and see lots of modified commits).

State the command in a way that isn't conductive to careless
copy & paste.

 just generated.
 
+If your system is behind a snooping HTTPS proxy, you might also have to
+make its SSL certificate known to curl, a system specific operation.
+If that's not possible for some reason, you can also disable SSL
+certificate verification in git:
+
+	git config [--global] http.sslVerify [true|false]
+
+The `--global` argument sets it for all git transfers of your local
+user, `false` means not to validate the certificate.
+
+If that still doesn't allow you to pull or push changes to the server, the
+proxy is likely tampering with the data stream, in which case there's nothing
+we can do.
