Add boundary case tests, with and without -L, for empty file; file with
one partial line; file with one full line.
The empty file test without -L is of particular interest. Historically,
this case has been supported (empty blame output) and this test protects
against regression by a subsequent patch fixing an off-by-one bug which
incorrectly accepts -LX where X is one past end-of-file.
