Subject: [PATCH] When explicitly selecting a templating engine, the raw
 template code is re-written to exclude the selection statement, by splitting
 the raw data, into lines, deleting the first line and then re-joining to new
 raw data.

The original code to join does not work with at least Python 3. This diff
fixes that.
