Removes all spaces in the beginning and the end of string s.

The result is identical to StringTrimLeft( StringTrimRight( s ))

    local integer l = -1

        exitwhen c == ""
        if c != " " then
            if l < 0 then
                set l = i
            endif
            set r = i + 1
