Trimming whitespace from CVS files in Repository

[Deever, Chris C.]

The initial import of SQL files that we are tracking with CVS were imported
with trailing whitespace and now I'd like to trim the extra whitespace from
all the files without affecting the modification histories of the files.

So, I wrote a small sed script to trim the whitespace from all the files in
the repository.  I tested the script on a test repository and found that
when I go to checkout the "fixed" modules I get the following error:

cvs [server aborted]: EOF in value in RCS file...

Since this approach seems not to work, is there a way to accomplish this
task without hosing up the repository?
