After cvs, emacs does not encode file correctly as dos

After cvs, emacs does not encode file correctly as dos

[Mark Mynsted]

I have a file called notes.txt.  It has DOS style line endings etc.
It is stored under linux.  When I view it from Emacs all was well,
i.e. Emacs correctly identified it as a DOS file and used the dos
encoding when visiting the file.  (I need the file to have the dos
line endings, etc.)  I next started to manage the file using CVS.  Now
the only way I can get Emacs to visit the file and display the line
endings, etc, correctly is to:

C-x <RET>c dos<RET>C-x C-f ~/doc/notes.txt 

Has anybody seen this behavior?  What is wrong?  Is this a CVS
problem, an Emacs problem, other?  How should I correct or mitigate
this problem?

What happens when you visit it normally, without C-x RET c?

Note that CVS might frob line endings.

The file is filled with ^M characters.  If I query the current coding
system, via M-x describe-current-coding-system  I get:

  - -- undecided-unix

 Kai> Note that CVS might frob line endings.

Is that what is happening?  Is there something I can do?

I think you mean that C-x RET c first will give you a file which
looks normally.  Omitting the C-x RET c will give you a file which
contains ^M at the end of the lines.

I think that's because most lines end with ^M but not all of them
do.  Can you look carefully whether really all lines end with ^M?

Emacs does not assume DOS line endings unless all of them are DOS
line endings.

Yes, it is exactly as you stated.

You are correct.  I had a line in my cvs controlled file, that
contained the cvs key word $Log$.  That key word was automatically
substituted with the cvs log for that file during the normal course
using cvs to manage the file.  Part of that "log" section, supplied by
cvs, did not contain a ^M character at the end of the line.

:-D

I removed the offending log and now my file looks normal while
omitting the C-x RET c!  Thank you very much!

You might want to check gnu.cvs.help to see why it happened and how
to make sure it won't happen again.

It is not available from my news server, but perhaps I could use
google groups or something to check gnu.cvs.help...  Thank you.
