[Bug-tar] Error in tar manual

[Andy Scheller]

Hello,

I've just noticed that
https://www.gnu.org/software/tar/manual/html_section/Portability.html#SEC151
has references to a 'xstar' program, but from reading the surrounding
text I believe this is a typo, and it should in fact say 'xsparse'
instead.
And it looks like this typo is indeed still present in the tar git
repository http://git.savannah.gnu.org/cgit/tar.git/tree/doc/tar.texi#n10128

Regards,
Andrew Scheller
