Summary:                    variable_watch with no command name will cause
READ_ACCESS for all variables in the current scope.
Description: 
When a variable that is being watched by variable_watch with no command name is
accessed, not only a message is printed out but all other variables in the
current scope will feel an READ_ACCESS and therefore execute watch commands on
them.

Steps to Reproduce: 
function(my_func)
  message("my_func")
endfunction()
variable_watch(a my_func)
set(a "")

variable_watch(b)
set(b "")

expected output:

my_func
* Variable "b" was accessed using REMOVED_ACCESS in: ....
  The value of the variable: ""
  The list file stack: ...

actual output:

my_func
* Variable "b" was accessed using REMOVED_ACCESS in: ....
  The value of the variable: ""
  The list file stack: ...
my_func
