Lars Kruse c81c20ab3b unify DIRTYCONFIG handling in shell and python plugins
The following issues were fixed:
* comparison too broad (e.g. "0" misinterpreted as "true")
* python: comparing string with number (is never equal in python)
* unwanted non-zero exitcode (compound command "&&" as last command in
  shell code block (e.g. "case" or "if" branch))
* access to unset variable (shell style issue)
