* A function to be called in the case where sourcemaps should not be tracked for a single node.
* This will still take care of leading/trailing comments.

* Note, however, that sourcemap tracking may resume for child nodes within the given
* node depending on the specifics of how the given node will be emitted.

* For instance, if this function is called with the node 'a + b', then we will not track
* the sourcemap for 'a + b' itself, but if 'emit' is called instead for nodes 'a' and 'b',
* then both 'a' and 'b' will have sourcemaps recorded if appropriate.
