For example, 4 properties: padding-top, padding-right, padding-bottom, and
padding-left
can be safely replaced with a single padding property.
Note that this inspection doesn't show up if the set of longhand properties is incomplete
(e.g. only 3 padding-xxx properties in a ruleset)
because switching to a shorthand may change the result.
For such cases consider the 'Properties may probably be replaced with a shorthand'
inspection.
