Use /epsilon as-is for /epsilon1 (#380)

Since epsilon1 (latin small letter open e / latin epsilon) already just
uses epsilon (greek small letter epsilon), it should probably look and
behave exactly the same. The transformations previously applied to
epsilon in epsilon1 resulted in spacing inconsistencies.

Closes #377
