privacy.but: document the Windows jump list.

Browse Source 
Jacob reminds me that that's another piece of saved data, less obvious
than the ones I'd already documented.

I'd actually forgotten myself _exactly_ which actions cause data to be
added to the jump list. But it's easy to check. The only functions
exported from jump-list.c are add_session_to_jumplist(),
remove_session_from_jumplist() and clear_jumplist(); the only one of
those that _records_ information (rather than removing it) is
add_session_to_jumplist(); and that is called in exactly one place,
namely at the end of load_session() in settings.c.

connection. Instead, re-enter the details by hand every time you do
it.
\H{privacy-jumplist} Jump list
On Windows, the operating system provides a feature called a \q{jump
list}. This is a menu that pops up from an application's icon in the
Windows taskbar, and the application can configure entries that appear
in it. Applications typically include menu items to re-launch recently
used documents or configurations.
PuTTY updates its jump list whenever a saved session is loaded, either
to launch it immediately or to load it within the configuration dialog
box. So if you have a collection of saved sessions, the jump list will
contain a record of which ones you have recently used.
An exception is that saved sessions are not included in the jump list
if they are not \q{launchable}, meaning that they actually specify a
host name or serial port to connect to. A non-launchable session can
specify all the other configuration details (such as fonts, window
size, keyboard setup, SSH features, etc), but leave out the hostname.
If you want to avoid leaving any evidence of having made a particular
connection, then make the connection without creating a launchable
saved session for it: either make no saved session at all, or create a
non-launchable one which sets up every detail \e{except} the
destination host name. Then it won't appear in the jump list.
(The saved session itself would also be evidence, of course, as
discussed in the previous section.)
\H{privacy-logfiles} Log files
PuTTY can be configured to save a log file of your entire session to
