Trivial thing that's bothered me for a while:

When a secfile is written with an entry_comment, the result looks like

fullscreen_mode=FALSE#deprecated

which I think could look like some special syntax, not a comment, to someone unfamiliar with the format.

I think it would be clearer with a few spaces:

fullscreen_mode=FALSE  # deprecated

Similarly

[cma]
number_of_presets=5#If you add a preset by hand, also update "number_of_presets" 

is a bit ugly.
