Subject: [PATCH] Revert "Fix savannah bug #63567"

Commit e89c7a45eb broke deletion from archives. The reported number
of bytes read is rounded to the nearest record anyway, revert the
commit and document the fact.

Reported by Ed Santiago. See
https://bugzilla.redhat.com/show_bug.cgi?id=2230127

* doc/tar.texi: Document the fact that --totals rounds up the
number of bytes reads to the nearest record.
* src/buffer.c: Revert changes.
* tests/delete06.at: Fix expected status code and stderr.

+Notice, that since @command{tar} operates on @dfn{records}, the number
+of bytes reported can be rounded up to the nearest full record.  This

 Finally, when deleting from an archive, the @option{--totals} option
 displays both numbers plus number of bytes removed from the archive:
