To be honest, I'm not sure.  I can't recall well enough to remember what
happened in DOS, or in Windows 9x.  I tried it on a co-worker's WinXP
machine, though, and it refused to perform the rename, stating that one
of the destination files already existed (I believe the error message
mentioned a "duplicate file name" or the like).  This behavior was the
same in both command.com and cmd.exe.

This construction works equally well with the copy command, BTW.  copy
asked me whether or not to overwrite the file with a "(Yes/No/All)?"
prompt.  (Only tested with cmd.exe as I didn't feel like performing the
experiment again.)

I'm not sure what you mean by input not mapping cleanly to output; care
to elaborate?
