That's similar except for the fact that there wasn't an alternative
method that would always work.

I respect others opinions, but I don't agree to the "better than 
nothing approach". I'm following this mailing list for a long time
and suggesting a full working solution over a half-baked or half-
working solution has always been a valid argument, so I don't see
why it shouldn't be in this case.

My interest is to have a good solution, not to block anything, so
I'll try to prepare a patch implementing path prefixing shortly.

Thanks,
