Bug#614287: add minimal __DATA__ etc. examples

[jidanni at jidanni.org]

Package: perl-doc
Version: 5.10.1-17
Severity: wishlist
File: /usr/share/perl/5.10.1/pod/perldata.pod

The tiniest example,
   while(<DATA>){print}
   __DATA__
   Bla
would do wonders to clear up this man page's discussion of __DATA__.
Same goes for the other __...__ items mentioned on this page, please.

(I had to use emacs'
(rgrep "__DATA__" "* .*" "/usr/share/perl" nil)
to figure out how to use it.)
