git does this too.

I think it's a little more VC-oriented than that.  Specifically, files
in .git/.hg are not versioned, while dot-files are.  So (AFAIK)
everybody puts the .ignore file in the WT and I think most users
version it.  Apparently git and hg have judged that .modules etc. are
more like .ignore than like the files in the .vcs directory.  Of
course, git is consistently inconsistent about this; the refs (which
live in .git/refs) are now versioned in the reflog.
