[PATCH] nmake distclean cleans too much from lib/Digest on Win32

I've been investigating some problems that I'm currently experiencing 
with Test-Smoke on Win32, and I've found that "nmake distclean" (which 
Test-Smoke runs between smokes) is deleting too much.

A fresh Perl (5.8 or 5.9) source tree contains

    lib/Digest/base.pm
    lib/Digest/t/base.t
    lib/Digest/t/digest.t

When you build it, lib/Digest/MD5.pm gets created.

When you distclean it, the *whole* of lib/Digest gets nuked:

    if exist ..\lib\Digest rmdir /s /q ..\lib\Digest
    if exist ..\lib\Digest rmdir /s ..\lib\Digest

Now when you try to rebuild that source tree (like Test-Smoke does) you 
get errors about "prerequisite Digest::base not found", and the tests 
being missing.

The attached patch removes the nuking of the lib/Digest directory.  The 
lib/Digest/MD5.pm file that was created during the build is explicitly 
deleted earlier in the Makefile anyway, so that'll still be deleted (as 
it should).

Was there any particular reason that the whole of lib/Digest was being 
nuked?  I can't see any.  It used to be an OK thing to do, I guess, but 
now that lib/Digest contains base.pm and the tests (changes 21807 and 
21809) I think the rmdir should go.

The patch needs to be applied to perl-5.8 as well as perl-current.

I've no idea if other platforms have the same issue or not.  Maybe they 
do since Makefile.SH contains:

    -rmdir lib/B lib/Data lib/Digest

in its "_cleaner2" target.  (It doesn't seem to explicitly delete 
lib/Digest/MD5.pm, though.)  Perhaps someone with access to other 
platforms could investigate?
