(and its probably got my earlier patch in it too , sorry about that)
this implements the search results window. If you do "Find in Files" , "search all open files" you will get a list of search results for your text. It only lists the first result in each file , not all of them so far. clicking on the entry in the search result window jumps to that line in the file.
no doubt needs more work to make it less annoying , but its a start I guess. Still need to do notebook for several results , and search again button.
searchresultview.pp is a blatent copy of messageview.pp
I had a guaranteed military sale with ed 209, renovation program,
spare parts for 25 years. Who cares if it worked or not?
