Description of Problem:
When I start a new session, it would be nice if
the recently visited folders (files) from the
previous session would still be be available in
nautilus' history sidebar.

Steps to reproduce the problem:
1. Open history sidebar
2. Browse around filesystem (for rationale:
specifically visit the folders which are relevant
to whatever you're working on these days)
3. Exit X session and restart, or close all
windows and restart

Actual Results:
Nautilus history sidebar has only current
directory (file).

Expected Results:
Nautilus history sidebar has same contents as when
shut down.

Additional Information:
The rationale is that the sidebar history panel
could very effectively serve the same purpose as
the most-recently-used-documents list commonly
found in the File menu in applications; not
persisting any history across sessions means, in
order to get similar functionality, things like
leaving multiple windows open for the stored
session (clutter) or explicit bookmarking (work).
