a28ea077f9 Use the correct value in the call to swab(3) with conv=swab. Previously,
dd if=/dev/zero of=/dev=null obs=23520 conv=swab
coredumped.

Please somebody review it, i'm not 105 % sure i'm understanding all
this mess correctly.

4ddfeabd8f Teach dd(1) about an option to write sparse files. Can be useful for
things like diskless clients' swap files etc.

af041bf3fd Pad the input buffer whenever sync is used, not just if the noerror flag
is also set.
Change osync to not to tack on an empty block if the input buffer is null,
    or an even multiple of the blocksize.
Also change osync to pad the output with nulls/spaces depending whether
   this is a block-oriented conversion or not (same as sync).

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

ad66f7ee71 Bruce says: "You have been programming in the kernel for too long :-)."
and he's right ... I forgot about this floating point stuff you can
use in user-land :-)

Increase precision of duration to microseconds.
No heuristics to avoid overflow in calculation needed - just depend
on DBL_MAX being a bit larger than LONG_MAX.

Use double instead of `struct timeval' in dd.h so that everything
doesn't have to include <sys/time.h>.

Fixed style bugs in recent and old FreeBSD changes.
