The small_vsprintf model is the vsprintf model.

In the case of %E, I believe that this is only actually used by strace
and api_fatal.  strace_printf has a 10,000 byte buffer, api_fatal uses a
4096 byte buffer.

I would welcome a patch if someone wants to modify cygwin to use the
vnsprintf model instead.
