operate on the selected line instead.
* Added CTRL-D and CTRL-U hotkeys to move down/up by half
a page.
* Added an `auto-width` flag to the elements of the
`line-format` array that indicates that the width of the
field should automatically be determined by the observed
values.
* Number fields used in a `line-format` now default to
being right-aligned.
Bug Fixes:
* Hidden values in JSON logs are now hidden by default.
