lynx-dev change to status line

[Eduardo Chappa L.]

Hello

When in advance mode, lynx cuts the address of the current link if this is
too long to be displayed, not showing the name of the document to be
accessed. This is important sometimes because one would not like to follow
certain links (say tar.gz or jpg in slow connections) or persons with
disabilities would not get valuable information from the status line.

The following patch changes this behavior to display the most possible
"useful information" For example:

http://here-there-is-a-very-very-very-very-very-long-url.com/and/it/links/to
/document.html

is displayed as:

http://here-there-is-a-very-very-very-very-very-long-url.c/.../document.html

the information is hard to find using the list of links and  not necessary
to do so, since it can be given in a better format. The following patch
acomplishes that. Of course more elegant solutions can be done.

The patch is against 2.8.2rel1
