Yes, it truncates to this on Mozilla in Slackware:
#!/bin/sh
ftp -i -n ftp.server.com <
...truncating after that first <.
Since Spartanicus and L. Blaisdell can't see it,
I think it's something specific to browser decoding.
I use <pre> a lot, and that's something I havn't run into
before.
I downloaded it and played with it a bit. The thing that
brings it back under Moz/Slack is using <<, as you
predicted. I suspect you'll just have to live with WGD's
complaint, but both > characters display under Moz. What

The other problem is that under Moz/Linux, the newlines you are
using inside the <pre> do not show up in the Moz display.
I had to go in with vim and add the newlines myself to get
the lines to display in the <pre> correctly.
