New Revision: 326027
URL: http://llvm.org/viewvc/llvm-project?rev=326027&view=rev
Log:
Cleanup __config indention NFC
This commit indents each level by two space characters, e.g.
#if defined(CONDITION)
# define _LIBCPP_NAME VALUE
#else
# define _LIBCPP_NAME VALUE
#endif
The simple #ifndef, #define, and #endif sequences are not indented, e.g.
#ifndef _LIBCPP_NAME
#define _LIBCPP_NAME ...
#endif
