+USAGE="<commit range> <commit-ish> [commit-ish...]"
+LONG_USAGE="COMMIT RANGE
+ A commit range is usually specified as <older commitish>..<newer commitish>
+
+COMMIT-ISH
+ A commit-ish is anything which can recursively be resolved to a commit; see 'gitglossary(7)'.
+

+ git is-in-range HEAD~4..HEAD~2 HEAD~5 HEAD~4 HEAD~3 HEAD~2 HEAD~1
+ < HEAD~5
+ = HEAD~4
+ = HEAD~3
+ = HEAD~2
+ > HEAD~1
