svn commit: trunk/busybox: archival include

[pgf at busybox.net]

Author: pgf
Date: 2007-09-07 13:28:25 -0700 (Fri, 07 Sep 2007)
New Revision: 19801

Log:
overload the existing '-q' flag so that if '-l' and '-q' are used
together, a "short form" listing (just pathnames) is generated.
change a few flag variables to "smallint" as well.
