debug-config emits stray comma
If I use
ART_DEBUG_CONFIG=1 lar -c prodgenie_nue_dune10kt_1x2x6.fcl
and pipe the outpout to a text file, strip off the stray lines on top and bottom, and
use the resulting file as a fcl script, I get a parse error due to a stray comma. It also
happens if I use the --debug-config command line argument. I tracked
it down to this line in an input fcl file:
/grid/fermiapp/products/larsoft/lardata/v06_00_00_rc1/job/larproperties.fcl:71 ReflectiveSurfaceDiffuseFractions: [ [ 0.5, 0.5, 0.5 ] ]
and the resulting output of --debug-config is this:
The parse error comes from the last comma. It looks like something's emitting a comma after every
array element, including the last one. There are two other instances of this in the same fcl document, but they look like the same problem.
I see this in art v1_18_05 -f Linux64bit+2.6-2.12 -q debug:e9:nu

This problem was originally reported as issue #12062, and it has been resolved. The question remains if it is necessary to back-port the fix to the
art 1.17 branch (currently it is on a ROOT6 branch). MicroBooNE has reported that they do not need such a back-port, but what is 35-ton's position?

It's not a big deal. I was testing v1_18_05 with ROOT6 and was running into other issues which made me stumble on this one. If no one's complaining about 1.17 I'd say we don't care. But if it can be fixed moving forwards with new versions it would be good.
