Boris Feld <boris.feld@octobus.net> [Thu, 31 May 2018 18:05:15 +0200] rev 38253
perftemplating: fix the revisions argument
Before this change, the argument passed to log where a string instead of a list
of string. This meant only single character rev were supported...
We now properly accepts argument of any length. We also make it possible to
specify multiple REV arguments in the same go.
