path: change the output format of ExampleSplit function

Browse Source 
At the moment the last output line of ExampleSplit- two empty strings- are being
trimmed from the output.  I have formatted the output of the function to avoid
whitespace trimming and show empty strings more clearly.

Fixes #23542
