Commas are supposed to be optional just about everywhere, including here.
Also, it works if you type 'concat("1")' which doesn't make sense if you 
go by the reasoning you've proposed.

What was happening was much more complicated, but essentially POV was throwing
away every second token inside the parentheses, but with some additional 
caveats that made it unable to parse the example with two parameters.  This
will be fixed in an upcoming beta. (and, more importantly, it is NOT a 
documentation bug, so no need to say anything about commas being required.)
