>|How risky is this for backward compatibility? With any change there is some risk. Has anyone ever used braces or hboxes to localize the effect of ` and ' transposition? The workaround is to use ! before the closing brace.

I believe the first modification I listed would have the desired effect, but of course any testing would be worthwhile.
