support setting empty values (sanely) & removing support for
space-gapping: '-o option= value' That is a very old feature (straight from 1998), but it is super surprising if you try setting empty values and instead get error messages or a non-empty value as the next parameter is treated as the value – which could have been empty, so if for some reason you need a compatible way of setting an empty value try: '-o option="" ""'. I can only guess that the idea was to support '-o option value', but we survived 17 years without it, we will do fine in the future I guess. Similar is the case for '-t= testing' even through '-t testing' existed before and the code even tried to detect mistakes like '-t= -b' … all gone now. Technically that is as its removing a feature replacing it with another a major interface break. In practice I really hope for my and their sanity that nobody was using this; but if for some reaon you do: Remove the space and be done. I found the patch and the bugreport actually only after the fact, but its reassuring that others are puzzled by this as well and hence a thanks is in perfect order here as the patch is practical identical [expect that this one here adds tests and other bonus items]. Thanks: Daniel Hartwig for initial patch. Closes: 693092
