>Description:
Runnig lintpkgsrc -r removes distfiles/.cvsignore and distfiles/CVS/*, which 
should be left in place.

lintpkgsrc did not do that a few months ago so I wonder if this problem was not 
introduced by the last update (or one of the last updates).

>How-To-Repeat:
% pwd
/usr/pkgsrc
% ls distfiles/.cvsignore
distfiles/.cvsignore
% ls distfiles/CVS       
Entries      Repository   Root
% lintpkgsrc -r          
Scan distinfo: .......................................... (10005 packages)
4 unreferenced file(s) in '/usr/pkgsrc/distfiles':
.cvsignore
CVS/Entries
CVS/Repository
CVS/Root
[...]
% ls distfiles/.cvsignore
ls: distfiles/.cvsignore: No such file or directory
% ls distfiles/CVS       
%
