commit 5dea0c1caaeb0d7f1280fd28c80c3c1bc10c34d0

    Simplify environment juggling by using fork() instead of vfork()
    
    xinit used to copy process environment in order to give client correct DISPLAY
    and WINDOWPATH variables. It was not possible to do it in client process because
    it was vforked, not forked.
    
    As vfork() usage was not entirely correct (manpage specifies that behaviour is
    undefined if there are any memory modifications between vfork and exec), switch
    to fork(), move setting environment variables to client process and and drop all
    the manual mucking with environment.

    Fix whitespace
    
    File was indented with mix of 8-space and tab symbols and inconsistently
    formatted. Apply more-or-less consistent formatting and reindent everything to
    4-space.
