Explanation of borders in the manual The explanation includes the limit case of maxinteger being a border. It also avoids the term "natural", which might include large floats with natural values.

Added option LUA_NOBUILTIN This option allows external code to avoid the use of gcc builtin macro '__builtin_expect' in the Lua API.

Optimization for 'n^2' Squares are much more common than other exponentiations, and 'n*n' is much more efficient than 'pow'.

Merge branch 'master' of https://github.com/lua/lua Adding file README.md to local repository.

Fixed bug of long strings in binary chunks When "undumping" a long string, the function 'LoadVector' can call the reader function, which can run the garbage collector, which can collect the string being read. So, the string must be anchored during the call to 'LoadVector'. (This commit also fixes the identation in 'l_alloc'.)

Details Added as incompatibility, in the manual, the extra return of 'io.lines'.
