[GRASS-dev] obtain the progress percentage of a command run from python

[G. Allegri]

I've seen that the grass.script.core.percent() module method wraps the
g.message -p command.
It's ok when the work is done within the python code, but how to grab the
progress emitted by a GRASS command (i,e, G_percent)?
There are many ways to run a command from python. What is the most
appropriate to obtain/pipe the percentage from the command... given it can
be done?
