Wouldn't this feature be similar to how Git converts line endings?

It would probably have to be configured per repo so that it doesn't mess with tab delimited files etc.

Auto CrLf is a terrible thing that can change the meaning of programs. Source control shouldn't be changing the contents of files (though a hook to format wouldn't be bad necessarily).

Auto CRLF is awesome for languages I use. Which ones can it change meaning in?

[MichaelGG]

Any language that allows string literals to wrap lines without normalizing it. Like C# or F#. Anything with HERE docs might do it, but Ruby and Python seem to normalize.
