Good summary. My original plan was to try to "make obsolete"/retire
and phase out core.autocrlf completely.
However, since e.g. egit/jgit uses it
(they don't have support for .gitattributes at all) I am not sure if this
is a good idea either. Opinions are welcome.

Unless I am wrong, that had been the default a long time ago:
Git for Windows (at that time msysgit) had core.autocrlf=true
by default.
While this is a good choice for many repos, some people prefer
core.autocrlf=input.
Others just commit files for Windows-based repos with CRLF,
and the advantage is, that "git diff" doesn't show "^M" somewhere.

I allways encourage people to set up a .gitattributes file.
Does anybody thinks that we can make core.autocrlf obsolete ?
