to explain it a bit more: at the moment you can define points/segments by
stdin input or a text file; that's nice.
the enhancement (two options: point or line, fixed distance) would be so
that no stdin or a text file input is needed.

as a workaround for points I've added a little addon:

Comment(by pvanbosgeo):
Somebody must have read my mind.. I was just trying to figure out how to
do this.v.to.points.
I only need points along straight lines, so using v.to.points (with
use=vertex and dmax option set to a distance) seems to work too, although
the results are slightly off from those created by the
v.fixed.segmentpoints.

I just posted in #2231 a diff to v.split that implements a flag allowing
to split lines according to a fixed distance. Combining this with
v.to.points use=node should give you the points as well.
