release 2.4.7pre4 - Thanks!

[Dave Madole]

Excellent work, Martin (and any others involved).  No more hangs, and
the more consistent
and complete messages at the different levels of verbose are great.  The
"why is a path included
or excluded" messages at -vv should cut the traffic on this list by
about 25% (I wish I'd had them
a couple of weeks ago).

I've been testing it all morning with a somewhat Byzantine set of perl
generated options and
so far no problems.  (And it may be my imagination, but it even seems
faster).

Thanks again,

Dave Madole
