Ah, makes sense now, but let me regurgitate:
According to src/Makefile.inc1, installword sets up INSTALLTMP with
some nifty files, along with the files previously in the obj tree
setup by phases such as bootstrap-tools.  Since these are defined
later on in the path before the user's ${PATH}, one doesn't shoot
one's foot off when updating the binaries, correct?

In my circumstance, I don't have an obj tree on the dest. host, but
I do have /rescue.   I could extract that on a first run and then
perform the later extractions with the updated tar (or just do it
all if /rescue/tar works anyway).  Does this seem decent?  Is there
a more elegant way?

Thanks for the heads up, Kris!
