Sorry, I don't understand how modifying or not modifying these files
affects whether they should be ignored (by putting them in
.gitignore).  Can you explain?

The way VC knows whether they might need to be added is via the
.gitignore file.  So the easiest way to solve your problem is to add
patterns to that file that would ignore the generated files.
Alternatively, maybe you can cause the Studio to generate them in a
special directory.

I build Emacs inside the Git repository, and that creates a lot of
files I don't care about.  They are all in .gitignore.
