The general rule is to preserve as much of
comments/whitespace layout as only possible.
It is not just for human eyes but it gets handy
when different versions of the file are compared.

The tool should make guesses to which
data item a comment belongs - for INI the rules
are quite straightforward (I wrote such a tool once).

The comments should not be accessible
from the application - they are comments
and not something application uses.

However, it may be useful to be able to /add/
a comment (as "value added on 2006/01/23")
programatically.
