There are a couple of alternates to consider here:

(1) If any of these args are mandatory, consider listing the param name
explicitly here, and only using the substitution string to hold the value --
e.g. how the suggest_url above treats the "client" or "gs_ri" or "sugkey"
params.
(2) Alternately, consider simply making the URL here something like:

{google:baseURL}_/contextualsearch?{google:contextualSearchVersion}{google:contextualSearchParams}

...and then having the TemplateURL expand that last into all the different
params necessary.  This makes for simpler code in TemplateURL.  (We could
probably make use of this trick for some of the other URLs above more than we
currently do.)

Went with (1), since several are mandatory and this makes that explicit.
