parser: --script delivers old-style keyword template

[neteler]

In GRASS GIS 7 the keywords need to be defined in separate lines. However, the actual --script output prints all in a single line:

r.to.vect --script | grep keyword
#% keyword: raster, conversion, geometry, vectorization

This will require an update in lib/gis/parser_script.c

[neteler]

Once fixed, also r70930 + r71048 (manual additions) need the respective update.
