To have it automatically updated when the buffer changes. I guess that's
what the font-lock is for. No?

It's not all. The intend is to highlight buffer's first line which is
not empty nor start with # character. Editing the buffer should update
this automatically.

So about your example, let's say that I later remove the leading comment
character "# " from the third line. Now that changed line should
automatically highlighted and the same highlighting removed from other
lines. I assume such things can be done with font-locks?
