So let's clarify what was the situation in 1.4 and what has changed in
1.6 .

<Up until 1.4>

Many of us are used to writing in extensions.conf:

  exten => 123456,1,AppFooBar(arg1,arg2,arg3)

But when you look at the result: 'dialplan show context-foo-bar' it
would look like:

  '123456' => 1. AppFooBar(arg1|arg2|arg3)

Thus when processing the dialplan from extensions.conf, asterisk would
silently translate commas to pipes.

People have tons of dialplans that uses commans. Simply dropping this
silent translation would break it. But this over-smart translation
caused all sorts of problem. Not to mention problems doing it properly
(when exactly? Where?)

This has been discussed quite a while ago for long in the devs list IIR
(sorry, can't find a reference) and was eventually decided that the best
alternative would be to both drop the translation and replace pipes with

IIRC supporting both commas and pipes was difficult. But I don't really
recall why. I'm too lazy to look into this right now.
