Actually, your note about the cross-platform potential issue, help me  
to find the solution:
r.SearchPattern = "^#[^#][^\x0A\x0D]*[\x0A\x0D]+"

That's for the comment line, and it avoids the use of the greedy dot.  
Besides, it gave me the solutions for the empty lines:
r.SearchPattern = "^[\x0A\x0D]+"

After a few tests, it appears to be cross-platform at lesat for the  
CR, LF and CRLF ends of line.
Thanks Charles for the inspiration.

Eric.
