I run dirvish from a wrapper script I wrote for my own systems;  it would
not be difficult to write a script like that to make the "20070822" daily
directories.  It would also not be difficult to make a lot of daily
directories in advance, that are empty until used.

I will ask the local perlmonger's group if there is a good way to 
replace the "mkdir" in the dirvish script with something that will do
"mkdir -p" properly, and that can go into a patch of dirvish, and a
future version of dirvish if enough dirvish users want to participate
to make that happen.
