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.)

Leaving out step 3. results in exactly the same thing. Thus Git doesn't
appear to be responsible for the ^M's. Thanks a lot for your effort on
this and my apologies for not taking the care to dissect this more
carefully as you suggested. Over to the Meld mailing list...

I didn't mean to shy you away ;)

Applying recent lessons form StackO'flow :P

Could it be that there is a ^M very early in the file (or rather
something else which isn't covered by dos2unix) so that Meld thinks it's
DOS and inserts line endings as DOS? At least that's what vim would do.

If there is i don't find it using Emacs, but Emacs may only show what dos2unix sees... Will post back the Meld insights (here's hoping!)

In any case, Meld people over there should know (or get to know) that

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,
