Stop Git from messing with my newlines

I'm sorry, but I just hate when Git is messing with my files... That's just not its job!

warning: CRLF will be replaced by LF in ... The file will have its original line endings in your working directory.

Local fix

The config responsible is core.autocrlf, and you can see where its set and to what value like this:

# This shows what it's set to now, and where
> git config --show-origin core.autocrlf

The solution is to set/change it to false, either by editing the file directly, or using the git config command:

# System level (might disappear with git upgrades?)
> git config --system core.autocrlf false

# User level (probably preferred)
> git config --global core.autocrlf false

# Repo level (no point, use .gitattributes instead)
> git config --local core.autocrlf false

Shared repository fix

For shared projects, others might not have set this or even want to set this, so to prevent issues there, creating a .gitattributes file at the root of the repo with the following contents should fix things:

* -text

Renormalization

For already messed up repos or working-copies, after changing core.autocrlf, you might be able to renormalize the files one of the methods described in this answer on StackOverflow.
