[mew-int 00473] Mew 2.0.52 -> 2.0.1

[Kazu Yamamoto ( 山本和彦 )]

I have released Mew 2.0.52 (beta). At this momemnt, Mew 2.0.52
includes bug fixes only, not new features.

I'm planning to merge the differences between 2.0 (stable) and 2.0.52
(beta) to 2.0.1 (stable), and will release it as stable.

If you volunteer, please give a try to Mew 2.0.52. If no bugs will be
found, I will release Mew 2.0.1 in the next week.

After Mew 2.0.1 (stable), I will add new features to the beta source
tree (which will be 2.1 stable finally).

Major changes so far:

* contrib/incdir now move messages in the "cur" directory as well as
  the "new" directory if the "-a" option is specified.
* Illegal Summary cache formant and unpredictable actions of "(" and ")"
  are fixed.
* The "Type 'I'" message is displayed in the minibuffer, not in the body
  of a message marked with 'T'.
* mew-case-guess-when-composed works well now.
* "Sort region" (C-uS) now revives.
* A header for a Bcc: message is now well-prepared.
* mew-thread-column is now obsoleted. Put 't' in mew-scan-form to
  specify the position of thread indentation.
* Asking Subject: before "Really send this message? ".
* The "phrase:addr1,addr2;" notation is allowed in Addrbook if and
  only if it doesn't recurse when expanded.
* Many other small bug fixes.
