Comment (by wenzeslaus):

 In r65294 I changed `exec` to `--exec`. This follows general long flag
 syntax which is already partially used in `grass.py`. I think it will be
 better to leave the "subcommand syntax" for the actual implementation of
 it. So now we have:

 {{{
 grass71 ~/grassdata/nc_spm_08_grass7/user1/ --exec g.region -p
 }}}

 The only alternative would be to go with majority there and use short
 flags, for example `-x` (`-e` is already taken for //exit after creating
 mapset//). But I'm not adding it because it should be primary used in
 script and programming and there you should use long flags anyway.

 It would be possible to go just with the short flags, as we do now with
 `-c`, `-e` and `-f` but this would go against the general trend of
 readability and I expect that we might change it in the future as we
 already support `--version`, `--config` and also all GUI selection flags
 can be used with two dashes.
