Prompt when there are too many results

[wtsnjp]

Currently, in list mode, when there are more results than max_lines, only a prompt asking if the entire list should be displayed, is shown.

$ texdoc -l plain
96 results. Display them all? (y/N)

To minimize the number of user interactions, I think it would be better to show the top max_lines results from the beginning and change to a prompt asking if more should be shown.

$ texdoc -l plain
96 results. Only the top 20 are shown below.

To minimize the number of user interactions, I think it would be better to show the top max_lines results from the beginning and change to a prompt asking if more should be shown. Good idea, IMHO. Only the top 20 are shown below. Or maybe 10? Not sure. I feel like usually the one I want is in the top 10. --thanks, karl.

20 is the current default value for max_lines. I can lower that default to 10 to accommodate this change.
