更新Git 2.11+（2016年第四季度，一年半后）：

  git config diff.wsErrorHighlight [old，new ，上下文] 
  

git diff / log --ws-error-highlight = < kind> 缺少相应的配置变量来默认设置它。这是添加到Git 2.11。

请参阅提交0b4b42e ，提交077965f ， commit f3f5c7f （2016年10月4日）作者： Junio C Hamano（ gitster ）。

I have the following output with git-diff.

- // sort list based on value    
+ // sort list based on value

How can I see easily see the number of removed tabs/spaces at the end of the line ?

解决方案

Note: Git 2.5+ (Q2 2015) will propose a more specific option for whitespace detection.

See commits 0e383e1, 0ad782f, and d55ef3e [26 May 2015] by Junio C Hamano (gitster).

diff.c: --ws-error-highlight=<kind> option

Traditionally, we only cared about whitespace breakages introduced in new lines.
Some people want to paint whitespace breakages on old lines, too. When they see a whitespace breakage on a new line, they can spot the same kind of whitespace breakage on the corresponding old line and want to say "Ah, those breakages are there but they were inherited from the original, so let's not touch them for now."

Introduce --ws-error-highlight=<kind> option, that lets them pass a comma separated list of old, new, and context to specify what lines to highlight whitespace errors on.

The documentation now includes:

--ws-error-highlight=<kind>

Highlight whitespace errors on lines specified by <kind> in the color specified by color.diff.whitespace.
<kind> is a comma separated list of old, new, context.
When this option is not given, only whitespace errors in new lines are highlighted.

E.g. --ws-error-highlight=new,old highlights whitespace errors on both deleted and added lines.
all can be used as a short-hand for old,new,context.

For instance, the old commit had one whitespace error (bbb), but you can focus on the new errors only:

(test done after t/t4015-diff-whitespace.sh)

Update Git 2.11+ (Q4 2016, a year and half later) :

git config diff.wsErrorHighlight [old,new,context]

git diff/log --ws-error-highlight=<kind> lacked the corresponding configuration variable to set it by default. That is added in Git 2.11.

See commit 0b4b42e, commit 077965f, commit f3f5c7f (04 Oct 2016) by Junio C Hamano (gitster).
