init: fix help string config options

[petrasovaa]

Add python_path and remove svn_revision as obsolete.

[neteler]

Isn't also a change here needed?

grass/lib/init/grass.py

Line 2184 in cd2c339

elif arg == "svn_revision":

and while at it, probably also here (the only other places with svn_revision)?:

python/grass/gunittest/multireport.py
38:        self.svn_revision = None
410:                "<td>{result.svn_revision}</td>"
500:            result.svn_revision = str(summary["svn_revision"])
559:        # x = [result.svn_revision for result in results]
561:            result.timestamp.strftime("%Y-%m-%d") + " (r" + result.svn_revision + ")"

python/grass/gunittest/reporters.py
163:def get_svn_revision():
874:            svn_revision = ""
876:            svn_revision = svn_info["revision"]
905:        summary["svn_revision"] = svn_revision

If you are just adding missing doc for python_path, please remove the unrelated svn_revision change. This will speed up the merge of the python_path change.
