-** This macro reallocs a vector 'b' from 'on' to 'n' elements, where
-** each element has size 'e'. In case of arithmetic overflow of the
-** product 'n'*'e', it raises an error (calling 'luaM_toobig'). Because
-** 'e' is always constant, it avoids the runtime division MAX_SIZET/(e).
-**
-** (The macro is somewhat complex to avoid warnings: The 'sizeof'
-** comparison avoids a runtime comparison when overflow cannot occur.
-** The compiler should be able to optimize the real test by itself, but
-** when it does it, it may give a warning about "comparison is always
-** false due to limited range of data type"; the +1 tricks the compiler,
-** avoiding this warning but also this optimization.)
