Tip #372: Remove unwanted empty or blank lines for english and chinese

This tip is inspired by tip #72 which titled 'Remove unwanted empty lines'.
:g/^$/d
==================
Well, if the line contains <Space> and <Tab>
:g/^\s*$/d
==================
If the line contains <Space> and <Tab> and chinese character <Space>, which takes two bytes, and the ASCII is 0xA1 0xA1.

:g/^\(\s\|　\)*$/d

Herein after the | I paste the `<Space> as a chinese character'.

:g/^[ \t|?]*$/d

Note the `|?' represents a single character which ascii is 0xA1, and inputed by
CTRL-VxA1
