Well, I must admit that I hadn't read this file, I just used my same
usual script where I had replaced bzr instruction by equivalent git
instruction. And, as a matter of fact, I had:

 $ git config --system --get core.autocrlf
-| true

That was just a test, I re-checked-it-out just after doing this.

Ok, I will do that. It surprises me that you need to tamper with the git
system setting that affect all the projects using git, just for the sake
of one project. I am using git also for fmtcount and I have some changes
pending, so I think that I will have to restore the original system
settings when I come back to fmtcount. That is not a very practical
solution.

I am quite novice with git, but just wondering whether it isn't possible
to get the same effect with affecting emacs only by writing in the local
config file (emacs/.git/config) some setting that would supersede the
global and system settings, e.g. you would have

[core]
autocrlf =

in the local config.

Another idea would be to set the eol attribute explicitly in the local
.gitattributes, which should not be too difficult using a wildcard.
