proposal: make -a flag the default behaviour for g.region
In my experience, when working with raster, having a precise resolution is the most important issue, while exact extension is less important. I often use existing vector data or bounds coordinates to determine the extent, but then have to use the -a flag to make sure that the desired resolution is kept.
I would like to propose that in grass7, the behaviour is switched, i.e. to make the -a flag (Align region to resolution) the default behaviour, and "align to bounds" the option.
I know this is a fundamental change in a fundamental module, but it's been itching for quite a while and I always find myself in difficulties having to explain to students why GRASS' default behaviour is the way it is...
