[Bug-tar] 1.31: No default checkpoint action

[Christian Weisgerber]

The documentation for GNU tar 1.31 claims in section "3.8 Checkpoints":

  The simplest value of action is `echo'.  [...]
  This is the default action, so running:
    $ tar -c --checkpoint=1000 --checkpoint-action=echo /var
  is equivalent to:
    $ tar -c --checkpoint=1000 /var

However, this is manifestly not true.  There is no default checkpoint
action.  Without an explicit --checkpoint-action=xxx argument, no
checkpoint action is taken, no default message is written to stderr.

I don't know if this is a documentation or implementation error.
