    Meta: Track pre-commit hook to build the manual
    
    It is necessary to check git status since we only want to stage
    hyperdrive.texi when hyperdrive.org is also staged.  If instead we
    relied on GNU Make's built-in timestamp comparison, `git add
    doc/hyperdrive.texi` would run when doc/hyperdrive.org is modified in
    the worktree but not among the files staged for commit.
