Clean up indention and propogate the required notices for H.S.'s regex
and expat-lite to NOTICE.

Leaves me a question;  this is in httpd-1.3 LICENSE;

  For the expat xml parser library component:

  Copyright (c) 1998, 1999, 2000 Thai Open Source Software Center Ltd
                                 and Clark Cooper

Grepping the entire tree, I find no reference to Thai OSSC/C. Cooper,
does this even belong here?
