tools/nxstyle.c: Add logic to detect check for left brace in first column, but preceded by a blank line. That should never happen for the outermost opening branch (but could happen with internal compound statements).

Browse source 
Consider junk.c for example:

    /****************************************************************************
     * xx
     ****************************************************************************/

    /****************************************************************************
     * Private Types
     ****************************************************************************/

    struct foo_s

    {
      int bar;
    };

    /****************************************************************************
     * Public Functions
     ****************************************************************************/

    int dofoo(int barin)

    {
      barout = barin;
      return barout;
    }

nxstyle not detects these problems:

    $ tools/nxstyle.exe junk.c
    junk.c:11:0: error: Blank line before opening left brace
    junk.c:21:0: error: Blank line before opening left brace
