内容：
svn的diff很好用，但是还不够好用，因为不像vim，可以很直观地看到两个文件的区别。Google了一下，发现一个还不错的解决方案( http://erik.thauvin.net/blog/news.jsp?date=2006-02-14 )，代码在这里: http://vc.thauvin.net/svn/linux/svndiff/svndiff.sh?view=markup ，但是有点小BUG。我FIX了一下，然后增加了一个小feature，允许在命令行后面跟上 "-r REV" 来指定与最新版本比较的版本号。代码如下：
#!/bin/sh

# svndiff -- svn diff with vimdiff.

PROGNAME=`basename $0`

if [ $# -lt 1 ]; then
    echo "Usage: $PROGNAME <file> [-r REV]"
    exit;
fi

filename=$1
pid=$$
TEMP=/tmp/tmp.$pid.$filename
pv=

if [ $# -gt 3 -a $2 = "-r" ]; then
    pv="-r $3"
fi
svn cat $filename $pv > $TEMP
vimdiff $TEMP $filename
rm -f $TEMP

@p.s. 2010.8.4  昨天给Erik发了封邮件，今天发现他已经把我的修改更新进去了:D
