Actually the change isn't obvious since we base it off of the file
extension, e.g. "--" for Texinfo files.
Perhaps we need an optional UPDATE_COPYRIGHT_YEAR_SEPARATOR environment
variable to determine what is used when converting:
2001, 2002, 2003, 2004
into:
2001 - 2004
For existing ranges we can use a capture group and preserve the existing
dash. The default if unset would just be the existing behavior.
I'll think about it for a bit.
