[gdal-dev] ogr2ogr: why only inserting the first file?

[Even Rouault]

Matt,

I doubt very much that specifying more than 1 source file to ogr2ogr has ever 
worked. I've checked up to GDAL 1.4.0 source code and ogr2ogr has only taken 
one source dataset at a time.

I also tried (with GDAL 1.6.0beta):
ogr2ogr -f gml test-merge.gml 094a01_3_0.gml
ogr2ogr -append -f gml test-merge.gml 094a02_3_0.gml

and the resulting test-merge.gml is not empty. However it contains only the 
features and layers of 094a02_3_0.gml (but I'm not that surprised as GML is a 
text format, so it doesn't support very well random access, merging, etc), 
whereas doing the same operations to shapefile output worked fine.
