Re: Font-lock seemingly interacting with insertion

Hi!

You could add your own custom property to `char-property-alias-alist'. This will work regardless if font-lock is active or not. This is how font-lock implements `font-lock-face', so you might find that it has the same drawbacks as `font-lock-face'.

One drawback that I can see is that some packages that convert buffers with syntax highlighting to other formats might not take this into account.
