   I think I did not communicate my concern clearly - let me try again. In the presence of a `~/.wsprops` file, setting `WSK_CONFIG_FILE=` forces (today) the CLI to ignore the property file and hence start with no properties.
   
   For example:
   ```
   > ls ~/.wskprops
   /my/home/.wskprops
   
   > WSK_CONFIG_FILE= wsk property get --all --apihost xxx
   whisk auth		
   whisk API host		
   whisk API version	v1
   whisk namespace		_
   whisk CLI version	2017-06-09T21:18:47+00:00
   whisk API build		Unknown
   whisk API build number	Unknown
   ```
   
   This feature is used by the catalogs to override the presence of a local file when installing catalogs.
