w3m-session display format [PATCH]

[Boruch Baum <boruch_baum@xxxxxxx>]

Currently, the listing of sessions (M-s, or M-x w3m-session-select) ends
each line with a list of all the urls for a session, which can make for
extremely long lines, and strikes me as pretty useless, since for
manually saved sessions, the user is already prompted for a name to
label the session.

The attached patch reduces the clutter, computation, memory usage, and
screen space by ignoring that information.

Note that the information is still available (and in a much more useful
and presentable manner) by pressing M-s a second time on any entry.

For your consideration.
