#3439: Unclear behaviour of v.buffer -s flag
-------------------------+-------------------------
Reporter: marisn | Owner: grass-dev@…
     Type: defect | Status: new
Priority: normal | Milestone: 7.4.0
Component: Vector | Version: svn-trunk
Keywords: v.buffer | CPU: Unspecified
Platform: Unspecified |
-------------------------+-------------------------
From the documentation is not clear if "-s" flag affects only corners of
line nodes or also corners of vertices. To make matters worse – output
varies depending on algorithm in use:
* with GEOS it affects only corners at nodes (line ends)
* with native it affects all corners (at nodes + at vertices)

As a minimum, documentation needs to be updated to indicate correct
behaviour and then a new bug should be filled to fix one of algo's to
match expected output.
