This PR improves `pp.oneline`, where it now preserves tags when truncating formatted syntax to a single line. Note that the `[...]` continuation does not yet have any functionality to enable seeing the untruncated syntax. Closes #3681.

# Tests of `pp.oneline`
|
|
|
|
These tests are only making sure that `pp.online` renders correctly as a string.
|
|
There is also logic to preserve tags that is not being tested.
