[GRASS5] v.profile for 5.1?

[H Bowman]

I was thinking about a module that would provide an elevation profile
along a track/road, and was curious to know if this could be easily done
with the vector improvements in 5.1.

Basically I'd like to have r.profile use a masked vector file to
automatically set r.profile profile=east,north[,east,north,east,north,...]

Currently this might be done with v.out.ascii or v.to.sites and some
text editor magic, but this is a pain and I'd suspect there'd be a limit
to the number of vertices you could feed the command line.

This might also be a way to label each point of a 5.1 vector with an
elevation attribute to make a 3d vector from a 2d vector and a DEM. (???)
