dd modifications

[Eric Thomas]

Dear Author,

I'm submitting patches that I made to the dd program and manual page. The 
changes allow the use of the conv=stat keyword, which will cause the program to 
display copy progress based upon the number of blocks read out of the total 
number of blocks that will be read. This is very useful when using dd to copy 
disk images to harddrives. The original fileutils-4.1 package was downloaded on 
January 20, 2003 from rpmfind.net. Please consider the inclusion of these 
changes for future fileutils distributions. Thank you,

Eric Thomas
