In cygwin on vista, 'wisotool2 liberation' fails with log

• wget -O liberation-fonts-1.04.tar.gz -nd -c --read-timeout=300 --tries=1 --retry-connrefused --header 'Accept-Encoding: gzip,deflate' \ https://fedorahosted.org/releases/l/i/liberation-fonts/liberation-fonts-1.04.tar.gz ...

A wget bug, perhaps?
