How to open the single line mode using re2?

[Jerry Chen]

in following page shows the re2 library support single line mode

https://code.google.com/p/re2/wiki/Syntax

but I always test failed, I use following code to open the single mode

RE2:Options option;

option.set_posix_syntax(true);

option.set_one_line(true);

I also test mutli-line mode, and it works.

So, can anyone teach me how to using single line mode using RE2, Thanks~!
