Thoughts about 'skip next block of included text'

Hello,

in some groups ppl. often quote the whole article and write their  
stuff below. After one or two article in a thread the first page in  
article pager contains only quoted stuff. The appropriate function to  
handle this seems to be 'PageSkipIncludedText', usually bound to ':'.

The man page says:

        PageSkipIncludedText ':'
                  Skip  to  the  end  of the quoted text-block in  
this article.
                  Quoted  text  is  everything   which   matches    
quote_regex,
                  quote_regex2 or quote_regex3.

The logic behind 'PageSkipIncludedText' is to search and jump to the  
next non-quoted line, which can be the first line currently displayed  
in the pager.

Unfortunately, the first line of each article is (usually) the  
quotation line or a header (from news_headers_to_display) which is  
not a quoted line => 'PageSkipIncludedText' doesn't work on the first  
page.

The second issue is that 'PageSkipIncludedText' only works once per  
article. If a quoted block was skipped, the first line in the pager  
is a non-quoted line => 'PageSkipIncludedText' doesn't skip the next  
block of quoted lines.

I'm not sure whether this is a bug or a feature. I think it's a bug.

With the attached patch 'PageSkipIncludedText' jumps to the first non- 
quoted line *after* the next block of quoted lines. One can now read  
the whole article skipping all the quoted stuff by using  
'PageSkipIncludedText' multiple times.

The patch is against the latest snapshot.
