CVS upgrade differences

[Rick Phillips]

Among other things I am the CVS admin at our company.  We are currently
using CVS version 1.11.2 and looking to upgrade to 1.12.13 to take
advantage of the "write-proxy" feature to better support some off-shore
development being done.

Before doing the upgrade of our actual CVS server, I decided to
prototype the upgrade on a backup system.  I took a copy of the current
repository on put it on the prototype running CVS 1.11.2.  I then did
several CVS operations to make sure everything was stable.  Among the
things I did was a checkout of our entire source tree.

I then upgraded to CVS 1.12.13, and repeated all my tests, including the
checkout.  

When I did a "diff -r --brief" on the two checkouts, I was surprised to
find 41 file differences.  

Below is a list of the files that differed after a checkout under CVS
version 1.11.2 and 1.12.13:  The problem always affect the first
occurrence of the pattern "*^I$", "*^I^I$" or "*^I^I^M$" (vi "set list"
format) and none of the ones after that (and there are ones after
that).  All 41 of these files display exactly one of  the differences
listed in the examples below. 

I know that in every case below, the difference is in a comment and
therefore won't create a problem compiling, etc.  BUT it really bothers
me that version 1.12.13 apparently cannot accurately reproduce these
files.  

Has anyone seen this problem before?  Have any other similar issues been
seen that might affect us in the future.

The following is an example from a skxmac2.c, see the RED highlight, note the 
unchanged same pattern in BLUE.


1.11.2 checkout:

$
/******************************************************************************$

1.12.13 checkout:

Also another pattern is from acct.h


1.11.2 checkout:
 *^I^IRevision 1.1.1.1  2001/08/13 19:22:21  maharig$
 *^I^IInitial import of DIAB-SDS compiler toolkit 4.3g$
 *^I^I$
 *^I^IRevision 1.1.1.1  2001/08/13 16:46:28  maharig$
 *^I^IInitial import of DIAB-SDS compiler toolkit 4.3g$



1.12.13 checkout:
 *^I^IRevision 1.1.1.1  2001/08/13 19:22:21  maharig$
 *^I^IInitial import of DIAB-SDS compiler toolkit 4.3g$
 *$
 *^I^IRevision 1.1.1.1  2001/08/13 16:46:28  maharig$
 *^I^IInitial import of DIAB-SDS compiler toolkit 4.3g$



One more pattern from the second acct.h in the list:

1.11.2 checkout:
 *^I^IRevision 1.1  2002/02/28 22:37:18  maharig$
 *^I^IInitial revision$

 *^I^I^M$

 *^I^IRevision 1.1  1994/03/29 00:42:23  fb^M$
 *^I^IInitial version^M$

1.12.13 checkout:
 *^I^IRevision 1.1  2002/02/28 22:37:18  maharig$
 *^I^IInitial revision$
 *^M$
 *^I^IRevision 1.1  1994/03/29 00:42:23  fb^M$
