   I agree with making it 1986-2012 everywhere uniformly.

   For files with new code, it would be nice if the first year in the
   pair could be the year of the file's creation - it's a little
   jarring to see something like tic6x-tdep.c with a 1986 date at the
   top of it.

The creation date of a file might not coresspond to the year when the
content of the file was written.  If tic6x-tdep.c was created based on
another files content, then it would be correct to add 1986 to the
list of copyright years.

   On the other hand, a copyright range like 2005-2012 makes it
   unclear if one is trying to say that that a particular file was
   modified each year in the range, or that it's "inheriting" the
   range from GDB as a whole.

AFAIK: The range is means that the copyright holder has asserted his
rights as a copyright holder each year during that period.  It has
nothing to do with if the particular file was modified during that
year.
