rm (FU 4.0) odd bug? rm -i accepting 's' as 'y'

[Pete Krawczyk]

address@hidden /tmp]# rm --version
rm (GNU fileutils) 4.0
address@hidden /tmp]# ls -al foo
ls: foo: No such file or directory
address@hidden /tmp]# touch foo
address@hidden /tmp]# ls -al foo
-rw-r--r--   1 root     root            0 Dec 27 14:44 foo
address@hidden /tmp]# rm -i foo
rm: remove `foo'? s
address@hidden /tmp]# ls -al foo
ls: foo: No such file or directory

Should this be construed as a bug, or is it a feature (perhaps 's' for
si) and forgotten in the documentation?

The best I can trace it to is that yesno() uses a regexp, which checks for
Yy or Nn.  But I can't figure out where 's' would cause it to remove the
file, whereas 'm' wouldn't.
