Git hook to call `git submodule update` automatically.

Triggered if the .gitmodules file is modified by changes being incorporated from a remote repository into the current branch (via git pull and thus git merge, or git rebase). This file should be named "post-rewrite", marked executable, and placed in .git/hooks/ within a local Git clone.

Note: could be modified [with a few edits] to be combined with https://gist.github.com/digitaljhelms/7901283

I'm not sure why, but (three years later) I tried to implement this as a post-rewrite hook and it didn't work. It does work fine as post-merge, though. Git version issue maybe?
