Re: How to avoid the ^M induced by Meld and Git

Esteemed Git users,

What i do:

1. Create a script.r using Emacs/ESS.
2. Make some modifications to script.r with the nice diff gui, Meld
3. Commit these modifications using git commit -am "my message"
4. Reopen script.r in Emacs/ESS to continue working.

The lines added (&/edited ?) using Meld all end with ^M which i 
certainly don't want. Lines not added/edited with Meld do NOT end with ^M.

What happens if you leave out step 3? If the same happens then Meld is
the culprit. (Unless you've set some special options, git does not
modify your file on commit, so this can't be git related.)

There are plenty of posts around about these being line endings used for 
windows which can appear when working on a script under a *nix OS which 
has previously been edited in a Windows OS. This is not the case here - 
everything is taking place on Ubuntu 12.04.

FWIW: the directory is being synced by dropbox; and in Meld, Preferences 
 > Encoding tab, "utf8" is entered in the text box.

Current work around is running in a terminal: dos2unix /path/to/script.r 
which strips the ^M's

But this just shouldn't be necessary and I'd really appreciate the 
reflections & advice on how to stop inducing these ^M's !

With thanks,

Karl
