Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

- Fix syntax
- Remove the (slightly wrong) duplicate explanation of the error condition
- Change reference to invalid multibyte character into invalid wide character
Instead of just deleting it, turn the original page into a general
overview of the multibyte character conversion functions, somewhat
similar to stdio(3).
