Clarify some behaviour, bringing schwarze@'s patch and mine closer together
(although I still don't have -M, which is a big piece).

First, the default search path is the cwd.  This will change to use -M
once I look over that code.

If MANPATH is specified, this replaces the cwd.

Both of these are augmented by -m.

If paths don't exist or don't have databases, they're silently ignored.
This makes perfect sense: you may be given a superset of possible paths.
The corner case of no paths (where, say, MANPATH consists of bogus paths
or the cwd is unreadable) simply means that no paths are searched.
