In Austrian German, (because "common" is relative to something e.g. geographical area, group of people)

-  "einhin" and
- "einher" 

are used, but usually pronounced 

- "eini" and (e.g. Er springt eini.)
- "eina" (e.g. Er springt eina.)

respectively, (unless you're in the Tyrolerean Uplands where the "h" is emphasized as a fricative: "eihi" and "eiha", respectively.)

This might seem very foreign someone unfamiliar with this, but it is not. Consider the ubiquitous “vorhin” and “vorher”. Whether prefixed or suffixed, it is merely a convention. Some dialects use one of the forms to express **both directions**, therefore not referencing the speakers location. However, in German, even in most dialects, the direction relative to the person is important.
