Major fight with spaces in arguments for `nmake`. The now smooth-running make process is a big bonus effect of this.
Kiss the `/Wp64` option goodbye.
Small improvements:
- Correct SVG MIME type is `image/svg+xml`.
- In ISO mode, suppress `width` and `height` attributes of embedded images (bitmap and SVG).
- In ISO mode, write `OL` class "num" or "alf" (not "1" or "a").
- For images (bitmap and SVG), write text in `title` attributes, not `alt` (an OBJECT has no `alt` attribute.)
- Cleaned up argument processing in `mkd2html`.
A really tiny tiny fix: The Vim modeline.
- How does an `<IMG>` element close? Hopefully just right now.
- Polishing the POSC Makefile.
