Description of problem:

installed updates:

emacs-muse-3.02.93-1.fc5
emacs-muse-el-3.02.93-1.fc5

With umask=027 (this is how we configured /etc/init.d/functions, which starts
crond, which performed the yum update), these two directories were unreadable by
the world and emacs doesn't start:
$ emacs test
Opening directory: permission denied, /usr/share/emacs/site-lisp/muse/contrib 

/usr/share/emacs/site-lisp/muse/{contrib,experimental}

How reproducible:
100%

Steps to Reproduce:
1.  rpm -e emacs-muse emacs-muse-el

2.  find /usr/share/emacs/site-lisp/muse/
/usr/share/emacs/site-lisp/muse/
/usr/share/emacs/site-lisp/muse/experimental
/usr/share/emacs/site-lisp/muse/contrib

Note that nothing owns it
rpm -q --whatprovides /usr/share/emacs/site-lisp/muse/{contrib,experimental}
file /usr/share/emacs/site-lisp/muse/contrib is not owned by any package
file /usr/share/emacs/site-lisp/muse/experimental is not owned by any package

rmdir /usr/share/emacs/site-lisp/muse/{contrib,experimental}

3.  install packages with tightened umask
umask 027
yum -y install  emacs-muse emacs-muse-el

Actual results:
find /usr/share/emacs/site-lisp/muse/ -type d -ls
1253220    4 drwxr-xr-x   4 root     root         4096 Jan  7 15:59
/usr/share/emacs/site-lisp/muse/
1343721    4 drwxr-x---   2 root     root         4096 Jan  7 15:59
/usr/share/emacs/site-lisp/muse/experimental
1343720    4 drwxr-x---   2 root     root         4096 Jan  7 15:59
/usr/share/emacs/site-lisp/muse/contrib


Expected results:
readable directories

Additional info:

Should these directories be "owned" by one of these packages and have
appropriate default permissions (and get removed?).  Subpackages are a pain, I
know, but I'm not an expert here.  :-)
