Paul Hinze fef60242b0 provisioners/shell: fix validation for args [GH-1949] ... The logic change in 57d4775140 introduced a bug where neither strings nor arrays provided as `args` for shell provisioners would pass validation. This fixes that problem along with a few extras: - split out arg validation into a private method - update comment describing valid args - add a few unit tests around config validation		2013-11-28 19:54:10 -06:00
