comment-region (and comment-line in Emacs 25) doesn't work on quoted lines

[cpitclaudel]

Tested in Emacs 24.5 and 25:

(with-current-buffer (get-buffer-create "*bug*")
  (erase-buffer)
  (markdown-mode)
  (save-excursion (insert "> test\n"))
  (comment-or-uncomment-region (point-at-bol) (point-at-eol))
  (pop-to-buffer (current-buffer)))

This goes from

> test

to

<!-- > test -->

(and the syntax highlighting is wrong), then to (repeating C-x C-; on that same first line)

<!-- <\!-- > test -\-> -->

and so on.

Let me know if I can provide more info! Thanks for the cool mode.

Thanks for reporting this. The inner > was being mistaken for the comment end because a space is allowed in comment closing (i.e., -- > could be a valid closing, but not in this case because the hyphens are part of the opening). As a result, the syntax table properties were incorrect and hence so was the highlighting and uncomment behavior.

I think it is fixed now, but please reopen if you find otherwise.

Brilliant, thanks!
