gol query outputs invalid csv

[nlehuby]

The gol query command outputs invalid csv when the requested tags are not set on some OSM objets

For instance :
gol query idf 'n[railway=subway_entrance]' -f=csv -t=name,ref,lat,lon > entrances.csv

outputs

t,id,name,ref,lat,lon
N,7924971323,"Les Agnettes",48.9230355,2.2859444
N,1519417728,"La Plaine Stade de France",1,48.929194,2.3568467
N,8224750689,"Rue Danièle Casanova",2,48.9299347,2.3565682
N,8224750688,"Rue Danièle Casanova",2,48.9299633,2.3565688
(...)

The fist line has 5 columns while the other ones have 6, because the first OSM object does not have the wanted ref tag

(tested with 0.1.8 version)

Thanks for submitting this!
CsvFeaturePrinter should output an empty value if the feature does not have a specified tag, in order to maintain the column structure.
A fix is coming shortly.

Fix is in dev, will be released as part of v0.1.10
