That makes it a lexically-scoped global variable, which we don't need
either. Can we have the internal function allocate on the stack, then
call cstring_to_text() on that, returning the text result? That does its
own palloc.

Or maybe better, save the starting pointer, compute the length at the end,
and call cstring_to_text_with_len()?  (It seems we wouldn't need
the nul-terminator then, either.)
