Review request for Asterisk Developers and Russell Bryant.


Changes
-------

Added enum to clarify return values. 


Summary
-------

ignore the last description parts of it were wrong.

When multiple ampersand-delimited prompts are passed to app_read, pressing # (without pressing other DTMF keys) merely cycles through the prompts until it reaches the last one. Then it will *finally* skip that prompt and return to the dialplan.  It would be nice if # returned to the dialplan immediately without cycling through the rest of the prompts.  

In app.c, ast_app_getdata is called to stream the prompts and receive DTMF input.  If ast_app_getdata() receives an empty string caused by the user inputing the end of string character, in this case '#', it should break from the prompt loop and return to app_read, but instead it cycles through all the prompts.  I've added a return value for this special case in ast_readstring().
