[PATCH] Nicer 'make dist' output.

[Ralf Wildenhues]

The output of 'make dist' has become more and more cluttered.
I am thinking of two choices to clean it up:
- either post all commands, i.e., each cp and all,
- or just post basically one line per directory,
- or post nothing.

The patch below goes the second way.  I've pushed it now, but I'd
appreciate comments, thoughts, and suggestions?

Thanks,
Ralf

    * lib/am/distdir.am (distdir): Hide the complex script
    used for computing the relative subdirs; echo the sub-make
    command.
