[PATCH 2/3] www_text/mirror: spell out "external index" and "public inbox"

[Eric Wong <e@80x24.org>]

"extindex" and "public-inbox" are project-specific terms which
are probably unsuitable for folks who are seeing this for the
first time.

Use "public inbox" when referring to actual public inboxes,
since "public-inbox" is merely the name for this particular
implementation and others have adopted the same concept (IMHO
the concept is more important than any particular
implementation).
