[winedump] Corrections for '//***' comments, and splitted extern "C" {

[Peter Berg Larsen]

Changelog:
        Currently a '//****' is matched as an /* comment - disallow a '/'
        in front of the '/*' match. An 'extern "C" {' can be split in
        several lines - allow '\n' as space, and lookout for the rest if
        partial found.
