man3: add a function's indicators

The patch addes function's indicators to a short description.

Lua 5.1 Reference Manual in "3.7 – Functions and Types" [1] describes
function's indicators and how to read this notation:

Each function has an indicator like this: `[-o, +p, x]`. The first
field, `o`, is how many elements the function pops from the stack. The
second field, `p`, is how many elements the function pushes onto the
stack. (Any function always pushes its results after popping its
arguments.) A field in the form `x|y` means the function can push (or
pop) `x` or `y` elements, depending on the situation; an interrogation
mark '?' means that we cannot know how many elements the function
pops/pushes by looking only at its arguments (e.g., they may depend on
what is on the stack). The third field, `x`, tells whether the function
may throw errors: '-' means the function never throws any error; 'm'
means the function may throw an error only due to not enough memory; 'e'
means the function may throw other kinds of errors; 'v' means the
function may throw an error on purpose.
