For a message that only gets logged at startup, I don't see any problem
with length.  I'd be a bit more conservative if a message could get
logged on every request.

I can see where those who repackage the server in commercial products
might not like having Apache URLs in all the messages.  And the URLS
would be a bit long.

If that won't fly, how about instead of URLs, adding message numbers?


HTTP0023: NameVirtualHost %s:%u has no VirtualHosts...

and add a section to the doc with the explanatory web pages for
