[bug-gnulib] quieter gnulib-tool?

[Karl Berry]

I was just wondering, would it be feasible/desirable to have an option
(--changes a la chmod?) to gnulib-tool so that it only reports files
actually created or changed?

I just added a single getopt module (getopt, plus its dependency
gettext) to Hello.  It went well, easier than I had feared (thanks
everyone), but now when I run gnulib-tool I get a lot of output (below)
even though nothing has actually changed.  I'd like to have an option
where, if the tool does nothing, it has no output.  The idea being that
that would make it easy to tell when something has changed.

Particularly troublesome are the misleading lines:
  Creating ./gnulib/lib/Makefile.am...
  Creating ./gnulib/m4/gnulib.m4...

Since they haven't changed, the script is smart enough not to update
them (yay), but still emits the above.

Wdyt?  Obviously it's not a huge deal, just thought I'd mention it.

Thanks,
karl

You may need to add #include directives for the following .h files.
  #include "gettext.h"
  #include <getopt.h>

Don't forget to add "gnulib/lib/Makefile"
to AC_CONFIG_FILES in "./configure.ac" and to mention
"lib" in SUBDIRS in some Makefile.am.
