Problems with RCS 5.7 on Windows XP (within emacs)

[G.R. Toro]

Hi,

I use rcs 5.7 in windows (from within emacs 20.7.1), and I have two 
problems.  My apologies if the problems are rcs-related rather than 
emacs-related.


The first one is that if I exit emacs before checking in the file I am 
editing, then the next time I try to edit the file, emacs tells me that 
another user (which happens to be myself) has the file locked for editing. 
I have to go through the routine of notifying myself that I stole the lock. 
Is there a way to avoid this nonsense?

The second question relates to the RCS_LF_ONLY environment setting.  About 
half of my editing of source files in Windows is with files that were 
originally created in Unix machines and still have only LF at the end of the 
line.  The other half are files created in Windows (with CR-LF at the end of 
the line).  I am currently using "RCS_LF_ONLY=something" in the environment 
and it appears that the rcs *,v files for Windows source files contain 
copies of every version of the entire file, instead of just differences.  Is 
there a way to get rcs to handle both file types efficiently?  Also, I 
cannot seem to find the place where the RCS_LF_ONLY option is documented.

Thanks,

Gabriel
