MSVC on Windows prepends padding instructions to functions for alignment (it currently uses the CC opcode for this and a 16-byte alignment for all functions by default). We currently preserve those instructions as "gap functions", but they should be safe to discard. We could add a pass that scans all gap functions and trims them by removing all CC (and even 90 as well) opcode.

Would it be possible to add support for excluding specific ports? I'm thinking this could be an additional argument passed to the script (a comma-delimited list of ports).

An example call could look like the following:

portforge.cr localhost 4440 4445 4442,4443

This would exclude ports 4442 and 4443.

The reasoning behind my feature request is that I might want to run a web server on
