Could we get rid of the damn exclamation mark (!)? Is it really normal to use it the way it's used in the English language files?
For most other languages it doesn't fit to well I guess, and Crowdin is nagging about it on every save - and also adds it to the TM even if it's not used in the translations at all (it's replacing the used dot in proposals).

T.ex:
$_['error_permission'] = 'Warning: You do not have permission to perform the selected action!';
->
$_['error_permission'] = 'Warning: You do not have permission to perform the selected action.';
