CVS cannot, in general, store record-structure files where the record
structure is significant.

It's not that simple.  You need to get and store all of the record
structure information, then you have to arrange to read the raw bits
from the file ignoring the record structure, and then reverse the
process when writing.  How one does diffs on that, I haven't a clue. 
It's also not at all clear how such a file should be handled when
extracting and/or modifying on a different system.

I think it's a fundamental design limitation.

In general, that won't work because there's no way to differentiate
newline characters that are supposed to represent record boundaries from
newline characters that are part of a record's (binary) data.
