I just realized that pulling a clean repository doesn't reproduce the 
problem correctly:

D:\rootpull>ls
CONTRIBUTORS  PKG-INFO  comparison.txt  hg        hgweb.cgi  rewrite-log 
  tests
COPYING       README    contrib         hgeditor  mercurial  setup.py
MANIFEST.in   TODO      doc
D:\rootpull>copy "c:\Program Files\Mercurial\hg.cmd" .
         1 file(s) copied.

D:\rootpull>ls
CONTRIBUTORS  README          doc       hgmerge    rewrite-log
COPYING       TODO            hg        hgweb.cgi  setup.py
MANIFEST.in   comparison.txt  hg.cmd    mercurial  templates
PKG-INFO      contrib         hgeditor  notes.txt  tests

D:\rootpull>hg
Traceback (most recent call last):
   File "D:\rootpull\hg.cmd", line 12, in ?
     from mercurial import commands
   File "D:\rootpull\mercurial\commands.py", line 9, in ?
     import fancyopts, ui, hg, util
   File "D:\rootpull\mercurial\hg.py", line 10, in ?
     from revlog import *
   File "D:\rootpull\mercurial\revlog.py", line 12, in ?
     from mercurial import mdiff
   File "D:\rootpull\mercurial\mdiff.py", line 8, in ?
     import difflib, struct, bdiff
ImportError: No module named bdiff

D:\rootpull>

I wasn't paying enough attention to exactly where the failure was. The 
hg file in the root of a mercurial repository isn't picked up by Windows 
as an executable file. When I copy in my hg.cmd(slightly tweaked hg 
script), I get the same error.

I guess I'll look at the patch and see how that works...
