Remove useless whitespace from styled string
The answer is to put the newlines at the start of each line, directly before the text.

&lt;string name="about_text"&gt;&lt;big&gt;&lt;b&gt;About&lt;/b&gt;&lt;/big&gt;
    \nLorem ipsum dolor sit amet and all that stuff...
    \n\nMore stuff.
&lt;/string&gt;


Therefore all the redundant whitespace appears at the end of each line (e.g. after "About") where it doesn't affect the appearance of your text.
