I'm not sure if you're asking if we test the feature in general (yes), or if we tested before whitespace at the end of a command line (no), or if I added a new test for this (also no) ?

[igalic]

if we already have tests for the feature, then we should extend the tests, too

(i'm not going to ask people to add tests where there are none to begin with)

The updated commit adds a test for a command line ending in whitespace. Hope I did it right!
