I think this argument sinks the whole `%%cat` idea.  The fact that
`%%cat` is sometimes used to write files is due to shell redirection,
not something inherent in the `cat` command (writing files with
“concatenate”?).  It's a good thing we can't have spaces in magic
names, so I can't suggest the amusing `%%cat >$FILENAME <<EOF` syntax
;).

Chuckles,
