Summary:                    Usage of Goto() in an included context can cause
unexpected behaviour
Description: 
I found this interesting little tidbit of usage behaviour yesterday when
writing some dialplan. Here is a simplified example of what I ran into:


[phones]

include => callControl
include => checkVoicemail

[callControl]
exten => preAuth,1,NoOp(well hello there)   ;   <-- this is what gets
matched when you do the Goto() from the checkVoicemail context.

[checkVoicemail]
exten => 8500,1,Goto(preAuth,1)

exten => preAuth,1,NoOp(this does not get hit as you might expect)

I disagree with the usage of the word "feature" because I can't think of
any practical reason why this would ever be expected or useful in sane
dialplan practice (i.e. why you would ever intentionally do the Goto() to
some other part of the dialplan by *not* specifying the context).

I do agree this is not exactly a *bug* but Asterisk dialplan is already
daunting enough that very subtle things like this cause all sorts of grief
for users. Documentation is good, but I'm in favour of making some of these
kinds of issues a little more obvious to the user.
