I don't know.  It's been normal behavior since the first time I noticed

One of the core developers might know.

Unless you add "dot" to your default path this won't work unless you
do python ./ImportSys.py

Same here.  ./importSys.py

The output below won't be relevant (in the context I'm looking for)

you can run the script without specifying what should run it or where 
it is.
