sfeed_opml_export: improve comment

In theory feed names can contain newlines, TABS, control-characters or start
with echo options like -n. This is not recommended and not checked.

URLs cannot have these characters: they should be percent-encoded.

echo is typically a shell built-in and fast, so this trade-off is done.
