We allow empty lines and lines that begin with ';' in .sym65. Lines with nothing but whitespace, or comments with leading whitespace, caused a warning. It can be aesthetically nice to line up the start of comments, and lines with pointless whitespace aren't problematic, so we now allow these without complaint. Added some samples to the 20170-external-symbols data file. No change to the test output.
