RE: why does occur depropertize matching lines?

[Drew Adams]

I got no response to this question (10/05), and I'm still curious:

    Occur now depropertizes the matching lines it copies to the
    occur buffer. Why?

    Previously, this wasn't done, and font-lock highlighting from the source
    buffer could often provide useful visual info in the occur buffer.

    For example, in Emacs Lisp mode, it's easier to see that a line is
    commented-out by its color than by checking to see if it starts with
";".
