Vincent, Hamish and all.
Maybe it would be easier to do PS with ps.map, convert it to pdf (for example with ps2pdf), then open in vector editor like Inkscape and add arrowheads manually.
On this topic I made small shell-script <d.arrowhead> that draw “arrowheads” of vector lines on the graphic monitor using d.graph (in fact, with any custom symbol) and optionally save graph file (to use with d.redraw / d.save etc.) and ps.map file (to use with ps.map “read” instruction).
This command makes red arrows with the custom symbol “arrows/arrowhead_1” (created by the script), and saves graph and psmap files
d.arrowhead -s test symbol=arrows/arrowhead_1 size=20 width=2 col=red graph=test.graph psmap=test.psmap
Output PNG with d.out.file and PDF with ps.map+ps2pdf:

Alexander,
thanks for your script. Out of the office for the entire week, I'll give
it a try a bit later.
My solution was based on a spatialite export of the vector map, then
some sql fiddling with vertices coordinates, and finally re-import
corrdinates and angles as a point vector. As Hamish suggested, I could
feed the wiki, although I agree it's rather a sqlite method than a
typical grass solution.
