 * 2002-03-14 DI restructured scan_profile and fixed bug handling comments
 * 2002-06-13 DI fixed handling of missing int parameter.
 * 2002-08-05 Matthias <[e-mail]> and Eric Lloyd <[e-mail]>
 *            Added support for -brf to place function opening brace after function
 *            declaration.
 * 2002-11-10 Cristalle Azundris Sabon <[e-mail]>
 *            Added --preprocessor-indentation (ppi)   if set, will indent nested
 *            preprocessor-statements with n spaces per level.  overrides -lps.
