I did as you suggested, asking the following question:

I'm contributing some work to GDB which entailed adding some new
files. The work was performed last year (2011) and was released
to a customer last year as well. When we did that release to our
customer, the standard GPL copyright was included at the top of
each new file with 2011 listed as the year.

Now that the file is being added to (upstream) GDB, the question
has come up as to whether 2011 should be listed in addition to
2012. My feeling is that it should, but it was suggested that I
ask you for guidance.

The response that I received from Donald R Robertson III is as follows:

In general, a work receives copyright protection from the time it
is fixed in a tangible medium of expression (e.g. saved on a hard
drive), and later additions receive protection when they are are
created as well. So the notice would generally read "Copyright
2011-2012" if the work had been modified in both years, even if it
wasn't published or distributed until 2012.

The better practice for large packages like GDB, however, is to
add new years to all files in the package, even if that file
wasn't modified in that year. So even if the file wasn't updated
in 2012, the notice should list 2011-2012, and the same would be
true for all the years thereafter.

I will follow the above guidance and revise the dates in the copyright
notice for the new files that I'm contributing to read "2011-2012".
