Hi,

Let's be creative!  I've cooked up a tiny little patch that does the 
following.

(1) Add an `-I' mode to apropos.c (apropos/whatis).
(2) If `-I', prepend a choice number to each matching manual.
(3) If `-I', instead of returning, ask the user for their choice.
(4) Pipe result into MANPAGER/PAGER/more(1).

Or by way of example:

% MANPAGER=head ./whatis -I find
[1] File::Find(3p) - Traverse a directory tree.
[2] find(1) - walk a file hierarchy
[3] Pod::Find(3p) - find POD documents in directory trees
Choose a manual number: 2
FIND(1)               General Commands Manual              FIND(1)

NAME
      find -- walk a file hierarchy

SYNOPSIS
      find [-dHhLXx] [-f path] path ... [expression]

DESCRIPTION
      find recursively descends the directory tree for each path

Thoughts on this?  My reasoning was people will probably go from 
apropos/whatis into man anyway.  Might as well save them the trouble.

My original thought was to add a `man' mode, like `apropos', that 
stipulated Nm~^key$ and routes to the first option.  I went with the 
above route to avoid the sticky part of sorting output properly.  Of 
course, with a few hours of work, the `man' mode is quite possible. 
However, mandocdb(8) would need to respect the man.conf arguments more.

Thoughts?
