UnxUtils xargs (mod) binary/source (GPLv2)
My Enhanced UnxUtils xargs

Binary: xargs.7z
Source: UnxUtilsSrc-findutils.7z
Source repository: http://rtoss.googlecode.com/svn/UnxUtils/

Changes:

• Added "-w" (--whole-line) switch (like "-d '\n'" in later versions, but this will quote the whole line)
• Added "-c" (--no-escape) switch. So that backslash will not be sorrowed.
• Removed "\" to "/" hack
