RedirectingAction->returnToArgs() has been renamed to returnToPrevious() to avoid confusion with the existing Action->returnToArgs which gives the arguments that would be used to pass to one of those. :)
Switching to the correct function call gets it working.
Thanks to Siebrand for catching it when I could debug it live!
Refactored some of the returnto handling code. It looks like we have several different ways of handling this in the software, icky!
Marked the session-based functions with fixmes (they'll stomp on other forms when multiple tabs/windows are used) and combined some commonish bits of code between ProfileFormAction and the group block & makeadmin actions where they're using hidden form parameters. Extended that to allow passing dynamic parameters (eg 'page') as well as static ones (action, target user/group).
* Mostly punctuation updates so that the same message is used consistently in all of StatusNet.
* Some cases of "Title Case" removed, because that does not appear to be used consistently.
