That's without the change though, right?

I found out why octave-mode-syntax-table misses this setting:
octave-mode uses a syntax-propertize-function to set the correct syntax
for quotes, it looks like that's needed because of the way backslashes
are handled.

It's not so easy to apply octave-syntax-propertize-function to
inferior-octave-mode to due prompts and output being in the buffer too.
Kind of a similar problem as the multiple mode stuff.
