t4051: add test for comments preceding function lines

When showing function context it would be helpful to show comments
immediately before declarations, as they are most likely relevant.

Add a test for that, but without specifying the choice of lines too
rigidly in the test---we may want to stop before and not include
"/*" in the future, for example.
