Since file-5.10 (end of 2011), libmagic identifies a C file in most cases as "C source" instead of as "C program". Nano's magic strings for some other files didn't match any more what file-5.32 currently produces, either. So, they have been adjusted, new ones added, and old ones deleted. This fixes https://savannah.gnu.org/bugs/?52445.
