counting: count words correctly also when --wordchars is used 

It should give the same result as 'wc -w' as long as the content
of 'wordchars' does not affect the counting.

This fixes https://savannah.gnu.org/bugs/?58123.

Bug existed since version 2.6.2, since the --wordchars option was
introduced in commit 6f12992c.
