I am the author of a precommit formatting library (https://github.com/Cosium/git-code-format-maven-plugin/). The hook formats the staged files.

Everything works fine except when using commit 'all' option.
With the classic git cli 'git commit -a' works fine. But with jGit, the hook is triggered before adding the files to staging:

```
if (!noVerify) {
				Hooks.preCommit(repo, hookOutRedirect.get(PreCommitHook.NAME),
						hookErrRedirect.get(PreCommitHook.NAME))
						.call();
			}

			processOptions(state, rw);

			if (all && !repo.isBare()) {
				try (Git git = new Git(repo)) {
					git.add().addFilepattern(".") //$NON-NLS-1$
							.setUpdate(true).call();
				} catch (NoFilepatternException e) {
					// should really not happen
					throw new JGitInternalException(e.getMessage(), e);
				}
			}
```

Because of that, the hook does not see any staged file and therefore does not format them.

I think that the files should be added to staging before hooks precommit execution.
