[GRASS-dev] i.spectral

Hello,

For those interested, I added an option to i.spectral to allow writing
output plot to a PNG image file.

Would it also be useful to add an option to write the gnuplot commands
to a file for editing and rendering? It already exists, but i.spectral
discards to file after render.
