Actually, what we found is that you personally didn't bother to look
for and find the customization options which would allow Emacs to
support such legacy code 100%.

That setup should be done only once.  When you complete doing it, and
save the customized options, they will be used thereafter for the
other files.  There are also facilities to make those customizations
effective only for files under a certain directory, in case changing
them globally is not what you want.

See my other message: this is already available.  You just didn't
bother using it or even reading about it.
