[Libreoffice] [PUSHED, partial] Remove NULL checks from delete

[Ivan Timofeev]

I have played with manual solving of this problem today... :-) There are 
the more interesting examples:

- else if(pUserMarker)
+ else
{
     delete pUserMarker;
     pUserMarker = 0L;
}

and

- if( GetPageNum() > 0 && pCntntAnchor )
+ if( GetPageNum() > 0 )
{
     delete pCntntAnchor;


Actually, catching these with regexp-search is hard...

I am agree. I think, it is better to find the problematic places by 
searching in the syntax-tree rather than in the source files.
