fixed.

5ac3b50142 - sync SYNOPSIS' with dd.c's usage' line; 
- correct spelling (prepositions).

3ee36a48b5 Fix a very old bug. When allocating the buffer and doing just a bs= transfer, 
hen we only need a single buffer equal to that blocksize in length.

331bd1b067 As suggested by Enami, rework the msgfmt logic a bit: 
- error out when an unknown specifier is used. Do this in f_msgfmt(),
before dd(1) starts operation.
- allow buffer_write() to flush the internal buffer even when NULL is
passed as parameter.

Some whitespace fixes too.

234ccf064a Add a new command to dd(1): msgfmt. The command modifies the 
output of the information summary returned by dd(1). This can be used
to specify messages in a more usable (or parseable) format like
human-readable values.

My intent is to re-use this for building image files and quick I/O
benchmarking.

37c4e1235f Remove the rif/rof options and add rump.dd. This makes usage 
consistent with other rump clients.  Copying between kernels is
done using the host pipe, e.g.:

  dd if=foo rof=bar skip=1 seek=1 => dd if=foo skip=1 | rump.dd of=bar seek=1

Also, the pipe idiom extends to copying between different rump
kernels, e.g.:

  env RUMP_SERVER=unix://srv1 rump.dd if=thefile \
      | env RUMP_SERVER=unix://srv2 rump.dd of=thefile

Pipe approach suggested by yamt (thanks!)

C_ROF|C_ROF.

6b03da8b7e Add two new operands: "rif" and "rof". They operate exactly like 
"if" and "of" with the exception that the communicate with a rump
kernel instead of the host kernel.

For example, to write stdout to /tmp/file.txt in a rump kernel namespace:
	dd rof=/tmp/file.txt

copy /file1 to /file2 inside a rump kernel:
	dd rif=/file1 rof=/file2

copy a snippet from /dev/rmd0d on the rump kernel to the host fs:
	dd rif=/dev/rmd0d of=save seek=1000 count=3

Eat that, usermode OS.

(I'll document the operands one I have some manpage to refer to
for rump client use).

0b16f71074 Avoid corrupting the dd(1) IO streams. This would happen by accidentally 
outputting to the files being manipulated by opening a file in the standard IO
descriptor space.  In particular, an output file unlucky enough to be sitting
on descriptor 2 (stderr) is certain to be corrupted.

Addresses PR bin/8521, and passes the recently committed regression test
"bin/dd".

458ed23412 As discusses a little while back on tech-userlevel: 
If stdout is a tty, use vis(3) to print any filenames to prevent garbage
from being printed if the filename contains control- or other non-printable
characters.

While here, sprinkle some EXIT_FAILURE and NOTREACHED where appropriate.
