cleanup: get rid of redundant assignments 'foo = foo' Redundant assignments were searched with: grep '^ *\(.*\) = \1$' `hg files` Some of these cases have resulted from earlier cleanup, like: foo = safe_unicode(foo) and later batch removing safe_unicode usage. See e.g. commit e35373106528b29461b7f5144780cb9ec79f765d . Note: two false positives occur: kallithea/tests/models/test_settings.py:39: setting.app_settings_value = setting.app_settings_value kallithea/tests/models/test_settings.py:42: setting.app_settings_value = setting.app_settings_value which is not a plain assignment but where 'app_settings_value' is a property method with side effects.
