That's all fine and dandy *but*:

1.) This is still *not* an official standard.

2.) Even it it were made a standard, it is not always possible to pick your
tools.

I think that most of the tools I use will handle the mixed line feeds. I am
not sure because I do most of my work on Windows. However, some of my work
requires that I use specific tools. There is nothing wrong with these tools
per se. They were designed to run on Windows and they work when they are
handed *valid* Windows text files. It hardly fair to say a Windows tool
designed to work with Windows text files is busted because it won't handle
Mac or Linux EOLs.

And as indicated once the EOL's are mixed it might be impossible to extract
the original format. And yes, sometime the format DOES matter.

I exit this thread now, I've got work to do ;-)
