buffer names of files and directories merely distinguished by <2>

[Dan Jacobson <jidanni@dman.ddts.net>]

Gentlemen, consider what happens with
C-x d somefile.txt RET v C-x C-b
You get
 MR Buffer           Size  Mode         File
 -- ------           ----  ----         ----
. % somefile.txt<2>      2448  Fundamental  ~/somefile.txt
  % somefile.txt          104  Dired by name ~/somefile.txt
That the buffer names are distinguished by a <2> and not by something
indicating say, one is a file, and/or the other a directory, is regrettable.
Sure one can find out easy enough, but it would be handy sometimes.
