Of course - the "crud" as you called it, isn't space delimited (per the
examples you included) - rather the stuff after the .html / .aspx etc.
This is often important in knowing what part of a site was visited.

If you really want to trim, notice that the .html/.aspx is usually
suffixed by a ? .. so replace the space above with a ? - odds are it's
the first in the line (is ? a valid filename character under DOS/Windows
?)

so:
	strings index.dat | grep ^Visited | sed -e 's/\?.*$//g' | less

might well do the job, if not - modify as above to ensure the URL is
kept too ..
