(c) does not equal "copyright"

[Mark Polesky]

Is this something to address? A lot of LP source files use (c) and not
"Copyright", despite this legal advice from GNU:

Always use the English word “Copyright”; by international convention,
this is used worldwide, even for material in other languages. The
copyright symbol “©” can be included if you wish (and your character set
supports it), but it's not necessary. There is no legal significance to
using the three-character sequence “(C)”, although it does no harm.
