[Bug-tar] closeopen() rationale?

[Bdale Garbee]

A bug filed a while back by one of the users of my Debian packaging of tar
noted that passing pipes via <() in bash on the tar command line had broken,
and Ingo Saitz later tracked this down to the introduction of closeopen() on
2006-07-03, but noted there was no reason given for the change.

I'd be pleased to understand what the rationale for the change was to document
why when I close this bug report... of course, if upon reconsideration you
want to revert the functionality, let me know that too.  ;-)
