mew-absfilter 1.37 へのパッチ その三

Mew でスパム・フィルター bsfilter を走らせる Elisp mew-absfilter.el のお話。本ブログで、mew-absfilter.el を最新の Mew (4.2.53 以降) に追随させる patch を公開していたのだけど、バグがあった。具体的には

(setq mew-use-suffix t)
(setq mew-suffix ".eml")

という設定に対して、mew-absfilter.el が bsfilter を上手く走らせられないというバグ。これは、保存したメールに拡張子 .eml を付けるという設定。拡張子を付けた時に、mew-absfilter.el が拡張子のついたメールを bsfilter に渡せなくなっていた。

この問題を修正するパッチを、問記事の末尾に載せる。対象は素の mew-absfilter.el 1.37。本ブログで提供している古い patch を当ててる方は、逆パッチして下さい。

mew-absfilter.el の設定、前パッチでの修正点 etc... は過去記事を参照されたし。
