in the old version 13560 calling some functions invoke the console.
others go to the document without finding and without invoking the  
all functions that happens to be written in one line without a new  
line are found...

in version 13585 the 2 first cases dont find and dont invoke the consol.

the one line functions are still found...

for whatever its worth...
