That's exactly what I meant by "use Wdired and perform query-replace with some
fancy replacement expression."

I know that a user can do it.  What I suggest is that we also "offer something
simpler for the common task of renaming a sequence of files."

A Windows user need not be familiar with Lisp sexps (and especially arcane
incantations using `\,' and \#).  It's great to have that capability, but we
should also offer something simpler for the common, simple case.

I haven't tried it, but from the doc string, it sounds like the kind of thing I
had in mind.

The doc for Dired should mention such a command (which should be bound to a
key), and it should mention that you can do fancier, more flexible replacement
using query-replace with `\,', `\#', etc.
