If `input' contains no matches [...] the result is a list containing
input’s content [...] as a single element.
This is a little implicit, if you consider such an input as having
nothing left to match over so it's as if there is no input (with a port
this confusion is a little clearer).
Clarify with an example in the docs, and also add tests.
