search_doc does not find phrases across multiple lines

[nathanncohen]

Hello !!!

Out of curiosity, I tried to look for a function I knew in Sage :

sage: search_doc("Floyd-Warshall")
html/en/reference/sage/graphs/graph.html:5797:<dd><p>Uses the Floyd-Warshall algorithm to find a shortest weighted path
sage: search_doc("Floyd-Warshall","pair")
sage: Graph.shortest_path_all_pairs?

I understand the current way to look for things in the doc is to grep it, and that for some reason we may need to keep our lines short ( less than 80 characters or so ).. I also understand that finding another way to search the doc ( if there is none available already ) may be some big amount of work. Even though, this really isn't the expected behaviour of the function, and I think we should do something about it.

Here's a patch implementing a "multiline" keyword for searches, so you can do

sage: print search_src('dhsw', 'betti', interact=False)

sage: print search_src('dhsw', 'betti', interact=False, multiline=True)
homology/chain_complex.py
homology/simplicial_complex.py

(With multiline searches, it doesn't return line numbers, just the file names.)
