Highlight to the reader that if another filter returns a
higher-precedence action value, then the ptracer will not
be notified.

The wording was incorrect:
It stated that 'eflags' may be the OR of one or two of those two flags,
but then a third flag was documented
(which according to the previous wording could not be used?!).
Moreover, the wording also disallowed using 0 (i.e., no flags at all),
which POSIX specifically allows;
I tested the function with no flags and it worked fine for me,
so I guess it was a problem with the documentation,
and not with the implementation itself.

I added the EXAMPLES section.
The examples in this page are incomplete
(you can't copy&paste&compile&run).
I fixed the one about TAILQ first,
and the rest should follow.

POSIX requires that the <regex.h> header shall define
the structures and symbolic constants used by the
regcomp(), regexec(), regerror(), and regfree() functions.
Therefore, there should be no need to include <sys/types.h>
at all.
The POSIX docs don't use that include:

This is implied by POSIX because it requires that these strings in
the locale definition file contain one symbol. Currently,
locale.5 does not document the concept of symbols, this change
glosses over that and just uses the term "single-character
string".
