This is hard to fix cause we strip comments before parsing quotes.
So doQuotes() see:

''''''
'''<!-- -->'''
'''''<!-- -->'''''

as:

'''''' 6 quotes
'''''' 6 quotes
'''''''''' // 10 quotes

We only consider the first five quotes and assumes everything before is
meant to be text. So 5 consecutive quotes are rendered as <b></b>
and the parser render above text as:

'<b></b>
'<b></b>
'''''<b></b>

Which is "correct".

A possibility would be to actually render comments as HTML comments,
but that can possibly be a lot of work for little reward. I would say
WONTFIX this bug and let user add a space before or after the comment
block so they can fix the bug by themselves :)

This seems like it's related... See the two source pages, especially the lowest
section, and look at the leading scare quotes. The diff, has whitespace
compression distorting the work around I employed. Basically
<pre>
...something ''''C''''
to
...something''' 'C''''
</pre>
made in 4-6 places. An true ascii diff utility will show those.

P.S. Ad hoc feature suggestion... this page needs a preview screen. Would be
really nice to have one in Wiki-email facility too.

P.P.S. -- Just one thought... spaces before and after comments not infrequently
break things... that good old wonderful grey box kind of break. In particular in
doing template coding. Why not parse six and render <nowiki><b><i>'</nowiki>...
you can't be parsing that many pages with five or six single quotes!

works fine here.

Still has the issue.

Text:
'''<!-- -->'''

Parse result:
<p>'
</p>

I believe the request is to have it render as: <b></b>

Might be a wont fix though.

oh, missed the ! part. yes, still a bug.
