Back to manual editing, then: the information obtained from r.support is 
stored in $LOCATION/cellhd/[mapname]. I don't really understand what you 
mean by default rows and columns: the default settings are stored in a 
file called $LOCATION/DEFAULT_WIND, but I am under the impression that 
this file is only valid inside mapset PERMANENT. Changing the # of rows 
and columns directly with r.support is only useful if you have incomplete 
raster files, otherwise g.region will do everything you want.

I seem to recall that ARC never accepted lines with more than 500 
vertices, so every line that is longer will be broken into segments.
