svn commit: r191670 - head/bin/rm

[Warner Losh]

Author: imp
Date: Wed Apr 29 18:08:18 2009
New Revision: 191670
URL: http://svn.freebsd.org/changeset/base/191670

Log:
  Implement ^T support for rm: now it will report the next file it
  removes when you hit ^T.  This is similar to what's done for cp.  The
  signal handler and type definitions for "info" were borrowed directly
  from cp.
