I thought hfs stripped the quoting brace's and just left the text inside.
there's no reason for HFS to strip such braces.
if it would be done everytime, it be like quoting never exists.
It is done in special cases.
Now, i could add {{append}} to such special cases, but maybe we can do in another way.
I will add a {{dequote}} macro, so when you want to execute your file, you can just
{{dequote|{{load|myfile.txt}} }}
Ok?
