Hello Martin,
thank you very much for your suggestion.

This looks like a perfect job for awk (gawk, or any POSIX implementation):
awk '/pattern/' RS= 'ORS=\n\n' filename
or a less terse and less cryptic version:
awk 'BEGIN{RS="";ORS="\n\n"} /pattern/{print}' filename
RS is a ``record separator'' and empty string means that empty lines separate
paragraph.
With gawk (GNU awk) and other advanced flavours of awk, you can have a
regular expression for RS.
See `info awk', or a book on the topic, to learn the details.
Thus I don't think it's much important to implement this fuctionality to
grep.
Have a nice day,
Stepan Kasal
