[PATCH] manifest: account for future cache in MiscIdx docdata

[PATCH] manifest: account for future cache in MiscIdx docdata

[Eric Wong]

We'll be storing private data inside the "" (empty string) key
of the JSON doc we use for store for manifest.js.gz generation.
This private data will allow us to reduce FS activity at and
speed up startup times, but some will also be in Xapian boolean
terms and values for searching and filtering.
