Do you think that makedumpfile should create dumpfile from STDIN without
any option like the following?

# makedumpfile dumpfile < dumpfile.tmp

I want to add the option of representing "create dumpfile from STDIN" clearly.
I think the following commandline.

* makedumpfile outputs a dump data of "flattening format (intermediate)" to STDOUT.
  # makedumpfile [-O | --to-stdout] /proc/vmcore

* makedumpfile creates a normal dumpfile from STDIN of "flattening format".
  # makedumpfile [-I | --from-stdin] dumpfile

  If creating a dumpfile from STDIN, makedumpfile of a remote host can
  create a normal dumpfile directly without intermediate file.

  # makedumpfile -O -cd31 -x vmlinux /proc/vmcore | ssh user at remote "makedumpfile -I dumpfile"
