+--long::
+ Always output the long format (the tag, the number of commits
+ and the abbreviated commit name) even when it matches a tag.
+ This is useful when you want to see parts of the commit object name
+ in "describe" output, even when the commit in question happens to be
+ a tagged version. Instead of just emitting the tag name, it will
+ describe such a commit as v1.2-0-deadbeef (0th commit since tag v1.2
+ that points at object deadbeef....).

--match <pattern>::
Only consider tags matching the given pattern (can be used to avoid
leaking private tags made from the repository).
