bug#21758: Translation Error in help info of "grep"

[Peng Zhang]

Hi,

I'm using GNU grep (version 2.20). When I get help with the command 
"grep --help", it prints the following information:

    ...
    -B, --before-context=NUM  打印以文本起始的NUM 行
    -A, --after-context=NUM   打印以文本结尾的NUM 行

This is totally wrong! It should be:

    -B, --before-context=NUM  打印文本及其前面的 NUM 行
    -A, --after-context=NUM   打印文本及其后面的 NUM 行


Thank you for your great jobs. Hope GNU software is better and better.
