.cvsignore and .svnignore do not apply recursively to subdirectories, do they?

In one project that uses autotools, I have "Makefile" and "Makefile.in" in
the top-level .gitignore. I would be forced to use this ugliness instead.

Granted, to write "/git", "/git-add", etc in .gitignore is not exactly
pretty, either, but the reason that it is so extra-ugly in the git code
itself is only because there are so many build products in a single
directory that cannot be caught by a glob pattern. In practice, you
usually have only a hand-full non-glob ignored files per directory; it
doesn't hurt to anchor them using "/frotz" style.

I would be concerned by this change.
