Fix commit 641a5b7a144 for "nbsp" output in SVG files

In commit 641a5b7a144, I removed "nbsp" characters from SVG files, not
realizing the SVG files were generated from GV files and that the "nbsp"
characters were caused by trailing ASCII spaces in GV files.  This
commit restores the "nbsp" SVG characters and adds a GV comment about
how the trailing spaces cause the "nbsp" output.
