* src/tail.c (file_lines): Seek to the previous block instead of the beginning (or a little before) of the block that was just scanned. Otherwise, the same block is read and scanned (at least partially) again. This bug was introduced by commit v9.7-219-g976f8abc1. * tests/tail/basic-seek.sh: Add a new test. * tests/local.mk: Reference the new test. * NEWS: mention the bug fix.
