+ Translation of GIT committish: ebe492ca408fb0d9abf80b94c56197eef8dc2f09

+ When revising a translation, copy the HEAD committish of the
+ version that you are working on. See TRANSLATION for details.
+
+we depend on an external entity here, which we cannot control. Suppose
+we go from 2.15.x to 2.17.x and put the documentation under "v2.17".
+For some time, Google won't have the new location in its index, so the
+search would get nothing. It would be better to keep "v2.15" in the
+search for a while and have a redirection from "v2.15" to "v2.17".
