bug#19262: rm command removes a read-only file without confirming when the stdin is closed

[Takahashi Mamoru]

Hello,

$ touch a; chmod 0444 a; ls -l a
-r--r--r-- 1 foo bar 0 Dec  3 14:25 a

$ echo a | xargs /bin/rm -v
removed 'a'

Or,

$ touch a; chmod 0444 a; ls -l a
$ /bin/rm -v a 0<&-
removed 'a'

Is this a bug or a feature ?

Best regards.
