Lexer must replace "minus followed by a number" with "plus followed by

It seems that the problem still exists.

In the following code :
local obj = setmetatable({}, {__sub = ...})
obj = obj-9223372036854775808

we are not able to write it as "obj+math.mininteger" as it would invoke
wrong metamethod ("__add" instead of "__sub").

As lexer does not have enough information to correctly choose
the type of number, it should be parser's job.

Or we should handle "9223372036854775808" as a special literal
in the language grammar.
