Ability to pass newline character for output files

[ALFNeT]

I've run into a situation where I need to make sure the output files are written with a specific EOL. In this particular case I need to read files with CRLF EOLs and write them in LF regardless of OS.

Ideally I think the EOL from the source files should be respected but I don't think that's a simple problem to solve at point so adding a new flag to specify the OEL for the output files feels like a good compromise.

I'm unsure if this is needed but many people or if this is the best way of going about it but I'm happy to make changes as required.

I never faced the issue, but that's a useful addition. Thank you. Could you add at least one test case so I can see how to use it? I am concerned that passing \n or \r\n will not be interpreted the way we want.

[ALFNeT]

Fair enough, I'll try adding a couple of tests in the next few days.

@elmotec I've added a test now. Let me know what you think or if you have any concerns.

I'll merge the addition. Thank you.

Out of curiosity though. How do you pass \n to the program at the command line on Windows? I've seen https://superuser.com/questions/150116 but that seems quite convoluted. I'd be interested to know.

Woohoo! Thanks for that @elmotec, much appreciated.

To be honest I'm not entirely sure what's the best way to do it in the command prompt, Powershell is a bit easier though you can pass `n
