After this patch `://` schemes are lowercase and enclosed in backticks.

  Markdown markup where applicable.

# PROXY PROTOCOL PREFIXES
The proxy string may be specified with a `protocol://` prefix to specify
alternative proxy protocols. (Added in 7.21.7)
If no protocol is specified in the proxy string or if the string does not
match a supported one, the proxy is treated as an HTTP proxy.
The supported proxy protocol prefixes are as follows:
## `http://`
Makes it use it as an HTTP proxy. The default if no scheme prefix is used.
## `https://`
Makes it treated as an **HTTPS** proxy.
## `socks4://`
Makes it the equivalent of --socks4
## `socks4a://`
Makes it the equivalent of --socks4a
## `socks5://`
Makes it the equivalent of --socks5
## `socks5h://`
Makes it the equivalent of --socks5-hostname
