gen-zam: Fix a bug caused by different behaviour of std::regex_replace under MSVC.

Browse source 
Under MSVC regex objects are multiline by default and there is no apparant way of changing this behaviour. Under clang/gcc regex is singleline unless std::regeX_constants::multiline is specificied.
This behaviour is assumed in Gen-ZAM.cc when auto-generating header files.

Example: https://godbolt.org/z/aP59x3EhT
