Use gunzip -c over gzcat in import-tars example.

zvpunry · spearce · commit c750da256a54 · 2007-02-21T11:09:57.000-05:00
Not everyone has gzcat or bzcat installed on their system, but
gunzip -c and bunzip2 -c perform the same task and are available
if the user has installed gzip support or bzip2 support.
