I did you see your messages, just haven't had so much time for handling
Emacs bugs recently.  I was going to forward it to the list before
replying, so thanks for doing that.

I mixed things up a bit, I meant to say

    (looking-at-p "[[:space:]\n]*quote\\_>")

The "\n" is needed because it typically has comment-ender syntax instead
of space syntax.  "\\>" matches end of word, "\\_>" is end of symbol.

I think relying on the mode's syntax table makes sense, though it
probably doesn't matter a whole lot either way.
