[jamming] Generated header files

[Diane Holt]

I distinguish generated headers by including them in a var (called
NO_HDRGRIST, but I suppose GENHDR or some such would have been better :)
then exclude the files listed in that var from the NoCare (and from getting
gristed with HDRGRIST, which explains the name a bit :)
