To expand on this, some major modes can fundamentally conflict with the
default noweb syntax. Here is a valid shell script *and* a valid noweb
reference to a block named EOF:
cat <<EOF>> file.txt
Hello
EOF
I hope this helps explain why the wrap-start and wrap-end options were
necessary to include more than a decade ago. In terms of actually using
them, it's a bit cumbersome, especially in Org mode buffers that use
multiple languages.
The second diff I sent (under the termux handle, accidentally) is my
preferred solution (:noweb yes <<< >>>). This would avoid the need for
new header arguments to be introduced while maintaining backwards
compatibility. It also feels natural to specify the two options
together: I can't think of a good reason to only need to specify the
wrap-end option.
