Earlier I submitted some fixes to hideshow.el to improve handling of
braces in comments (bug#8036). These fixes were incomplete and in one
case, incorrect. The attached patch improves hideshow.el further:

1. The previous patch made hs-find-block-beginning quit searching if a brace was
found inside a comment. This patch ignores that match and keeps searching.

2. There were some false positives of (looking-at hs-block-start-regexp) if the
point was at a commented-out brace. This patch wraps all instances of that in a
function to check for comments.
