Would it be possible to support a `with` approach with init?

Would it be possible to support a with approach:

with gsetup.init(gisdb, location, mapset, grass_path=gisbase):
    # Run GRASS code here

where finish() is automatically called after the with block?

Yes, it would! See #1834 for solution for notebooks (where with is not that useful). A similar approach can be used to implement a context manager to support usage with with.

In #1829, I documented the return value of init as something which can change. Now it is session file (rc file) path. I think the original idea is that user uses that to delete the file because there was originally no finish function.
