voxforge download script is corrupted on OSX Catalina

[bytosaur]

in voxforge/download-data.sh in Line 19: curl $VOXFORGE_DATA_URL | grep -o '<a .*href=.*>' | sed -e 's/<a /\n<a /g' | sed -e 's/<a .*href=['"'"'"]//' -e 's/["'"'"'].*$//' -e '/^$/ d' | grep tgz$ > $ZIPS

on my System (OSX Catalina): the "\n" inserts an "n" in front of the ZIPS urls and stops further processing. the error is detected by ls in the extract_tgz.sh script...

after removing it i still get the message "tar: failed to set default locale"... however the script unpacks everything and moves the wavs to the right folder...
