Fiddled with it some more this morning and found that removing lines that contained comments did help.

Removing:
"-" followed by text would save a line.
"######" lines like these would save 2 lines.
" " blank space & blank lines made no difference.
"---" with no text following made no difference.

Even with these items stripped from my test file, I was only able to save 1385 lines. In a normal SR map I might have achieved 13000 removed lines est out of a 46000 line map file. This would certainly help, but would not solve the problem for very large maps.

In the next version I will add an option to minimize file size which will strip blank lines and comments.
