Summary:                    Option U() functionality is not equivalent to
application documentation
Description: 
App documentation for Dial() option U() suggests that gosub calls "routine"
x and arguments are delimited with ^. Instead, option U() treats x as a
context and calls for extension s and priority 1 in it, and arguments are
delimited with either a comma or ^.

Debug:
    -- Executing [123 at default:1] Dial("Console/dsp1",
"Local/100 at weasels,,U(context,123,arg2)") in new stack

'Answer'
    -- Executing [100 at weasels:1] Answer("Local/100 at weasels-15c7;2", "") in
new stack
    -- Called 100 at weasels
    -- Local/100 at weasels-15c7;1 answered Console/dsp1
[Jun 24 17:57:45] DEBUG[10603]: app_stack.c:240 gosub_exec: Channel
Local/100 at weasels-15c7;1 has no datastore, so we're allocating one.

core show application GoSub (1.6.1.1) says
Gosub([[context,]exten,]priority[(arg1[,...][,argN])])

That is the way app GoSub actually works. It doesn't start at s,1 but
where it is told to start. U() works in a macro manner (goes to "s,1" in
given context), and does not work like GoSub.

The best solution would be to have U() work exactly like GoSub to avoid
two different behaviors.
