Renumber copyright clause 4

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.

Document incomplete support of [=equiv=] and collation for ranges.

Back out non-collating [a-z] ranges (r302594).

Back out non-collating [a-z] ranges (r302594).
Instead of changing the whole course to another POSIX-permitted way
for consistency and uniformity I decide to completely ignore missing
regex fucntionality and focus on fixing bugs in what we have now,
too many small obstacles we have choicing other way, counting ports.
Corresponding libc changes are backed out in r302824.

remove collation support for a-z ranges here too.
It was implemented for single byte locales only in any case.

1) Following r302512 (remove collation support for [a-z]-ranges in libc)
remove collation support for a-z ranges here too.
It was implemented for single byte locales only in any case.

2) Reduce [Cc]flag loop to WCHAR_MAX, WINT_MAX here includes WEOF which is
not a character.

3) Optimize [Cc]flag case: don't repeatedly add the last character of
string2 to squeeze cset when string2 reach its EOS state.

4) Reflect in the manpage that [=equiv=] is implemented for single
byte locales only.
