Runtime improved by 5% or so, and getAnnexLinkTarget moved up, otherwise
not a lot of change. keyFile is looking like an optimization target,
although its percent of the runtime actually reduced. 
However that's specific to this repo which has a lot of URL keys that
contain '/' and so need to be escaped.
