IIRC one reason to use wiki/ and w/ instead of
"direct" URLs
(
en.wikipedia.org/Xenu) was to allow for non-article data at a later
time (the other reason was to set noindex/nofollow rules). Looks like
we will use that space after all :-)
That may be one reason, but I think the main reason is to avoid
problems with articles called things like "index.php". /wiki/ is a
dummy directory, there's nothing actually there to conflict with, the
root directory has real files in it that need to accessible.
