[GRASS-dev] v.in.gshhs - bogus horizontal lines

Thanks for your v.in.gshhs GRASS 6 port.

I have a problem: when importing full GSHHS extent, strange horizontal
lines through the whole longitudal extent are present in the output
GRASS vector map, which are *visible only in v.digit or QGIS*, but never
on the regular wxGUI map display or X monitors.

To reproduce please import e.g. gshhs_c.b, zoom to it in wxGUI, then
open in digitizer and compare. Also please notice that *in QGIS those
bogus lines are always visible*.

I suppose this is related to the GSSHS data extent 0 - 360 vs. GRASS
-180 - 180.
