[PATCH] fix zfdir -r

[Han Pingtian <hanpt@linux.vnet.ibm.com>]

First, This patch try to fix the problem that 'zfdir -r' works just
like 'zfdir': they both show contents of current directory.

Then, with this patch if 'newdir' in 'zfdir -r newdir' is different
to the dir in last 'zfdir dir', the effect of '-r' will be canceled.
