config: In saving style 2, save deleted options too.

Browse Source 
Previously, ELinks set the OPT_WATERMARK flag in all deleted options
when config.saving_style was 2, thus mostly preventing them from being
saved.  This had the unfortunate consequence that if you started with
no elinks.conf, set config.saving_style = 2, deleted some built-in
option (e.g. a URL rewriting rule), saved the settings, and restarted
ELinks, then the built-in option would reappear.
