Converting multiple exten => lines to using same => in Asterisk dialplan

Last week I wanted to start changing some 1.4 based Asterisk dialplan to a 1.8 based Asterisk system, and in that process wanted to convert lines like:

exten => _NXXNXXXXXX,1,NoOp()
exten => _NXXNXXXXXX,2,GotoIf($[...]?reject,1)
exten => _NXXNXXXXXX,3,Dial(SIP/foo/${EXTEN})
...

into using the same => prefix:

exten => _NXXNXXXXXX,1,NoOp()
 same => n,GotoIf($[...]?reject,1)
 same => n,Dial(SIP/foo/${EXTEN})

In order to do that, Mike King helped me out with the following regular expressing which I used in vim:

%s/exten\s*=>\s*[^,]\+,\s*[n2-9]/ same => n/g
