[PATCH 2/6] search: drop longer subject: prefix for search

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

We only document the "s:" anyways.  While the long name is more
descriptive, the ambiguity makes agnostic caching (by Varnish or
similar) slightly harder and longer URLs are more likely to be
accidentally truncated when shared.
