It sounds about right. But C89 is, after all, almost 20 years old.
Being constrained by small memory environments is one thing, but
arbitrary limits older than some of the programmers writing in Lua are
another thing entirely. :-) I would expect that any decent modern
C99 compiler should be able to handle much larger strings.

Good thought. Maybe an array of such strings, each limited to 4K?
Writing a small Lua program to read in text (say, Lua source) and spit
out such a C array would be a good exercise, I might go play with
