> I suspect this happens because sometimes I edit the files on my Linux box and 
sometimes on my Windows box.

If I remember correctly, RCS (and the earlier SCCS systems) were designed to 
work with source code (i.e. text files).  They determined file changes based on 
lines added or deletes and had a fixed length internal buffer used to read each 
line.  From what I've read in this discussion, I think the issue is that the 
'^M' characters may not be seen by RCS as an EOL.  If that is the case, RCS will 
read the whole file as a single line and large files (>65KB) may not be properly 
handled.

Use dos2unix and unix2dos to convert the files and you will probably eliminate 
the issue.
