Hi,

I applied a similar patch like this to Gnulib a while ago.

Basically, the use of this in files:

    # eval: (add-hook 'before-save-hook 'time-stamp)

modifies the global before-save-hook for Emacs, i.e. even after closing
the file. This caused some annoyance because it wouldn't work with this
in your Emacs init file:

    (setq enable-local-variables :safe)

The solution to this is to use:

    # eval: (add-hook 'before-save-hook 'time-stamp nil t)

so it only enables it on the current buffer.
