st: wordcount() undocumented limitation?

[Rob Ploutz-Snyder <robploutzsnyder@gmail.com>]

Happy Friday Statalisters.

I bumped into an unexpected blip with the wordcount() function that
I'm puzzled by..  It seems to stop part-way through a long string, so
I must have hit some (undocumented?) limit of the wordcount() string
function.

It seems strange to me that the wordcount() string function shouldn't
produce the same result as the extended macro function..  maybe I'm
missing something?

Here's code to try as a do file:
