[mew-dist 28726] format=flowed

[Kazu Yamamoto ( 山本和彦 )]

Hello,

I have implemented the encoding of format=flowed and fixed several
bugs of the decoding.

There is a new option called mew-use-format-flowed. If
mew-use-format-flowed is t, a draft message will be encoded with
format=flowed IF NECESSARY (see blow).

The value of mew-use-format-flowed is default to t.

When mew-use-format-flowed is t, citation is in the flowed style.

>> Grand parent level
> Previous time
This time

If mew-use-format-flowed is nil, citation is in the old style.

> > Grand parent level
> Previous time
This time

When composing message, the encoding of format=flowed is done if any
lines are over mew-flowed-fold-threshold (78) and the long lines are
folded by mew-flowed-fold-length (70).

Delsp is "no" for "US-ASCII", "ISO-8859-1", etc. That is:

A long long long long long long long long long long long<natual SPC>
long long long line

Delsp is "yes" for "ISO-2022-JP", etc. That is:

JapaneseJapaneseJapaneseJapaneseJapaneseJapaneseJapan<additional SPC>
eseJapaneseJapaneseJapaneseJapaneseJapaneseJapaneseJapanese

Note that the decoding of format=flowed is always done. Use "_" to
toggle line styles.

I have committed this code to the CVS. If you kindly make a test, it
would be appreciated.
