Hey all,

git fetch --dry-run modifies the repository if --unshallow is passed:

$ git --version
git version 2.1.4
$ git fetch --dry-run --unshallow

remote: Compressing objects: 100% (6843/6843), done.

Resolving deltas: 100% (24564/24564), completed with 317 local objects.

I actually tried --dry-run --unshallow in order to find a way to detect in a script if the current git repository is shallow or not.
Better suggestions to find this out are very welcome.
