What's with the extra whitespace at the beginning?

[Sheridan Rawlins, 2011/11/23 20:10:07]

It outputs with proper indentation for the C++.  I'm not sure we need the
temporary C++ to show proper style, only valid C++ syntax.  Let me know if you
want me to scrap the indentation.

[James Hawkins, 2011/11/23 20:29:22]

Yes, get rid of the indentation here and elsewhere.

[Sheridan Rawlins, 2011/11/24 01:17:46]

Done.
