Description
When `CURLOPT_INTERFACE` (or the command line tool's `--interface` option) is
set with one of the documented prefixes (`if!`, `host!`, `ifhost!`), that
binding is not part of the connection reuse key, so a later transfer asking
for a different source can silently reuse an existing connection and go out
from the earlier transfer's source address
