less

less升级到了406版，修了两个bug，然后本地改了一个一直让我很头疼的问题——more重新支持+开头的文件名了。

现在仅剩的问题是more对控制台的支持。只需要改1行（加1个字符），不过感觉有点太hack了。

less is a very popular command line tool that is distributed with a lot of *nix distributions. Thanks goes to David Wolfskill (our postmaster) who helped the test.

The current plan is to MFC less(1) before 6.2-RELEASE’s freeze, but because the date is near, we may want to change the plan.
