We do stick to the RCS spec except with respect to binary deltas and 
extra expansion options (the latter shouldn't really affect a parser, 
but may affect the rendering of the final file).

However some RCS parsers are very inflexible with regards to the exact 
format, especially the parsing of new keywords, of which we use several.

As Arthur said in this case it's best to use the cvsnt rcs wrappers to 
parse the file, which will always give you the correct result.  Ideally 
don't use tools that try to parse the RCS files directly as these are 
prone to breakage.
