cabal init should create a .gitignore with dist-newstyle in it.

[Kleidukos]

It's quite irritating to initialise new projects and fall in the same trap each time: dist-newstyle is (rightfully) caught by git when one adds the newly created files. This trips quite a large proportion of newcomers I mentor.

A nice thing would be to have git support through a --vcs=git flag so that people who don't care about it don't get their folders cluttered.
