  39 resized to be the same size as the snapshot.  If the snapshot is smaller than
  40 the backing file, the backing file will not be truncated.  If you want the
  41 backing file to match the size of the smaller snapshot, you can safely truncate
  42 it yourself once the commit operation successfully completes.

 919 Read and print up to @var{size} bytes from ring buffer character
 920 device @var{device}.
 921 Certain non-printable characters are printed \uXXXX, where XXXX is the
 922 character code in hexadecimal.  Character \ is printed \\.
 923 Bug: can screw up when the buffer contains invalid UTF-8 sequences,
 924 NUL characters, after the ring buffer lost data, and when reading
 925 stops because the size limit is reached.
