The flag as mentioned above has been introduced in August 2008 and is in use 
since then to enable those extensions that would cause compatibility problems 
if the user is not aware of the feature in advance. This currently the keywords
%d% %e% %d% %h%

BTW: I forgot to mention that the prs command has new keywords :d: and :DY: 
for the same reason.

given the fact that the SCO sccs does not support unlimited linelength, I am 
sure I would immediately compile my SCCS and thus could make use of my history 
files that use the executable flag. I did not yet have contact with people who 
use the SCO feature, so I cannot tell how I would decide in case I receive mail 
from a former SCO user.

This is done by the Solaris based source which is my source.

Do you know of such implementations?
