We normally follow the GNU standard for copyright notices, which is

It says no comma.  It also says do not use a dash between years, but
instead list all the years individually.  See the main gcc directory
for a myriad examples.

My understanding is that none of this makes any legal difference.  I
think it's more or less up to the Ada maintainers whether they want to
strictly adhere to the GNU standards or not.
