[texhax] Inter-sentence space with amsthm

[Joel C. Salomon]

I’m playing with amsthm, and want to define a theorem style like:
	Example:**To avoid lithobraking, most rockets…
where the ‘**’ is the wide space TeX puts between sentences.

The eight argument to \newtheoremstyle is the “head space”; and I know I
can give it an explicit (inter-word) space, ‘\newline’, or a dimension
like 0.5em.  But what is the size of the inter-sentence space?
