Merge branch 'js/vscode'

Add a script (in contrib/) to help users of VSCode work better with
our codebase.

* js/vscode:
  vscode: let cSpell work on commit messages, too
  vscode: add a dictionary for cSpell
  vscode: use 8-space tabs, no trailing ws, etc for Git's source code
  vscode: wrap commit messages at column 72 by default
  vscode: only overwrite C/C++ settings
  mingw: define WIN32 explicitly
  cache.h: extract enum declaration from inside a struct declaration
  vscode: hard-code a couple defines
  contrib: add a script to initialize VS Code configuration

+Configuration for VS Code
+=========================
+
+[VS Code](https://code.visualstudio.com/) is a lightweight but powerful source
+code editor which runs on your desktop and is available for
+[Windows](https://code.visualstudio.com/docs/setup/windows),
+[macOS](https://code.visualstudio.com/docs/setup/mac) and
+[Linux](https://code.visualstudio.com/docs/setup/linux). Among other languages,
+it has [support for C/C++ via an extension](https://github.com/Microsoft/vscode-cpptools).
+
+To start developing Git with VS Code, simply run the Unix shell script called
+`init.sh` in this directory, which creates the configuration files in
+`.vscode/` that VS Code consumes. `init.sh` needs access to `make` and `gcc`,
+so run the script in a Git SDK shell if you are using Windows.
