(and thus the default), always use strcasestr(). Discussed on tech@
with schwarze@. While here, fix the apropos.c usage() message to be
consistent with apropos(1) and clean up the EXAMPLES in apropos(1).

* Bugfix: Use all arguments, not just the last one.
* Use 'Nm~' instead of 'Nm,Nd~' to match OpenBSD behaviour.
* For the progname, accept '^whatis', not '^whatis$' to ease testing.

of the mandoc databases, as suggested by kristaps@.
Given the well-structured code, this is surprisingly simple.
This changes the mandoc.index database format.
Run "sudo mandocdb" to regenerate your databases.

This is from a patch to tech@ as critiqued by schwarze@, checked in to

but a few serious things as well:
* -M overrides MANPATH
* -m prepends to the path
* put back database close calls that got lost in mandocdb
* missing sys/types.h in manpath.c, needed for size_t

This is necessary since an array of records can have duplicate record
numbers in different mandoc.index files.
The volume [right now] is just the index of the parsed mandoc.index in
the manpaths. This is sensible because the order of the manpath is
significant (it's the order of duplicate-named manuals displayed by
man(1)) and is thus not likely to change.

(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.

directories containing mandocdb(8) databases. Some changes follow:
(1) don't support -M yet;
(2) fall back to cwd if no prior manpath has been specified;
(3) resolve manpages using realpath() to prevent consecutive chdir()'s
over relative paths;
(4) note where further error-reporting is required;
(5) fix leaking memory on exit in several cases.

submitted to tech@ on 16/11/2011, 01:39. It has been updated to account
for the logical-operator functions and to avoid keeping a live pointer into
the DBT value, which is not guaranteed to be consistent across calls into
the bdb library.

apropos [search_type[,...]=]substring
apropos search_type[,...][,i]~regex
... and expression evaluation must take the search type into account.
This allows to:
* drop the global -I option and
* drop the enum match, just using a boolean int.

set of keywords already exists is a bad idea, so reuse the mdoc(7)
macro names as apropos(1) search types. This is a gain in brevity
as well. Some time ago, kristaps@ agreed in principle.
The search type bit field constants are used by both mandocdb(8) and
apropos(1) and should better stay in sync, so give them their own
header file.
