Thanks, I attempted to do that by installing the attached patch into GNU 
'tar'.

I got confused by the two Gnulib files build-aux/bootstrap and 
top/bootstrap. Although top/bootstrap says "The canonical version of this
 script is maintained as build-aux/bootstrap in gnulib", it's really in 
top/bootstrap.

More important, build-aux/bootstrap exists separately from top/bootstrap 
only to support packages that don't have bootstrap-funclib.sh; and yet 
build-aux/bootstrap invokes autopull.sh and autogen.sh, both of which 
require bootstrap-funclib.sh. One way to work around this problem would 
be to remove build-aux/bootstrap (and the machinery that generates it), 
thus requiring all downstream projects to add autogen.sh, autopull.sh, 
and bootstrap-funclib.sh. Another possibility would be to rename 
top/bootstrap to top/bootstrap.sh (so there aren't two confusing files 
with the same basename), and to fix top/gen-bootstrap.sed so that it 
inlines autopull.sh and autogen.sh as well as inlining 
bootstrap-funclib.sh. Or perhaps you can think of a better fix (maybe 
giving ./bootstrap --pull and --gen options instead of having separate 
scripts?).

Another idea: if we're going to break 'bootstrap' up into pieces, 
perhaps it'd be better for GNU tar to have these new files in a new 
directory, i.e., boot/autogen.sh, boot/autopull.sh, 
boot/bootstrap-funclib.sh, instead of autogen.sh, autopull.sh, 
bootstrap-funclib.sh, so as to keep the top level simple. Is that easy 
to arrange?
