Now you've confused me again.  What do you mean by \r?  Are you saying 
there are some Mac files with only \012 or with only \015?  That is are 
you speaking as a Unix/Linux/Windows user or as a Mac user?

This is why it's better not to use \r and \n at all in this context.

I wasn't talking about writing files, I was talking about writing the 
regexps that are used for reading files. (But as the section I quoted 
from Perldoc points out, there *are* issues with writing files if you 
want to use them with some network protocols :)
