codeintel_scan_exclude_dir does not seem to work #49

I tried this :
"codeintel_scan_exclude_dir":["/build/", "/min/","/node_modules/","_doc","output","/^/"],
in javascript, but when I try to navigate to a symbol that is defined in multiple places, I get the wrong one (in an excluded path). A quick scan of the code seems to indicate that the setting is not used
and, while we are at it, what is the format expected here ? is it regular expression ? if yes,
does "/" signify the opening delimiter, or a "path" character ?
