The definition of what is "text" and what action to take upon check-in / check-out of text is two sepearate things.

I could see it as beneficial as a per-project or even as an overall git-policy to say "checkin-as-LF" - "checkout-as-LF" to overcome interoperability issues when more tools gets UNIX* based.

Which is where I see .gitattributes come into play. -> A rule that says files with extension .prj and of type "text" shall not see any conversion.

In this way almost all "text" over time get a proper format and the remaining brain-dead tools that continue to save in CRLF format will not destroy the sane LF format.

If anything gets defualt I would vote for LF. But overrideable.

My editor-of-choice does eol auto-sense. If I recall correct it scans the first 200 lines and counts number of CR,LF,CRLF and based on this judge the actual eol character used. But not all editors are that sensible :-(
