PATCH 1/1 err.3: clean up description of error message source

man-pages version: latest git repository
why:
In the second paragraph of DESCRIPTION section, one of the sources of error messages is incorrect: the four functions obtain error message only from errno, and "a code" is just relavant with errc() and warnc(), which are not present on Linux. see http://www.unix.com/man-page/freebsd/3/ERR/ .

Then, the third paragraph becomes a duplicate.
