Fix commit 641a5b7 for "nbsp" output in SVG files

bmomjian · bmomjian · commit 6e80951f49f3 · 2024-11-26T13:08:13.000-05:00
In commit 641a5b7, 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.
