This changes the calendarspec parser to allow expressions such as "00:05..05", i.e. a range where start and end is the same. It also allows expressions such as "00:1-2/3", i.e. where the repetition value does not fit even once in the specified range. With this patch both cases will now be optimized away, i.e. the range is removed and a fixed value is used, which is functionally equivalent. See #15030 for an issue where the inability to parse such expressions caused confusion. I think it's probably better to accept these gracefully and optimizing them away instead of refusing them with a plain EINVAL. With a tool such as "systemd-analyze" calendar it should be easy to figure out the normalized form with the redundant bits optimized away.
