Well this is why I didn't want to write it, also it's more like
concept/idea rather than a patch.  Again new users should not be
surprised by this behaviour, so a line of warning would be nice, but
if it sounds like description of bug...  Maybe a footnote "This is not
a bug!" at the end (yes, this is a joke).

> Not sure what you mean by "hardcoded" faces.

Quote (for example) RET character (C-q RET), then do 'describe-char'
on it and you'll get something like "hardcoded face: escape-glyph" in
the description.

About that change 'face -> 'font-lock-face in table.el, I would
probably need to report another bug/wishlist thing, am I correct?
