Agreed.  With many of the names, I have been wondering though whether we
should distribute them at all in arbitrary directories.  For example,
most scripts don't make that much sense outside of the toplevel or the
build-aux directories.

Then again, changing the current behavior here is quite likely to break
some existing package setups, and even silently and only upon 'make
dist' (so it might never show up for the developer), so that I'm not
inclined to change this lightly.

Documenting the existing behavior better sounds like a good idea to me.

Thanks for the report,
Ralf
