Big Sky :: vimmer必読！読み込みの遅いvimscriptを見つけ出す方法

を見てもらうとして、Linux版(gtk)だと「--startuptime=result.txt」じゃなくて「--startuptime result.txt」じゃないと怒られます。

$ vim --startuptime=result.txt
VIM - Vi IMproved 7.2 (2008 Aug 9, compiled May 16 2010 17:49:57)
オプション引数の後にゴミがあります: "--startuptime=foo"
より詳細な情報は: "vim -h"
$ vim --startuptime result.txt -c quit
$ head foo

何かの間違いの可能性もあるので一応自分の:versionの結果を貼っときます。

追記

「他の引数の形式と違うから」という理由でバージョン7.2.286から変えられたらしいです。
