Any program, when asks to print their version, only prints that, and then
stops.
hugo checks the config (and prints a warning message if not found), and
proceeds to generate the site!
Yet, the user just wanted to check the version.
This patch makes sure hugo stops after printing the version.
The pflag package used in hugo has to use the "=" sign
for double dash options such as --source. Thus the original
example `--source ~/mysite` is already incorrect. Adding
the = sign though woul not fix things in this case, since
`--source=~/mysite` does not get resolved to /home/username/mysite,
but looks for the ./~/mysite directory within the current directory.
To resolve this, either the directory name has to be changed in
the docs not to use the "~" sign, or have to change to use the
single dash version of the command line flag. The latter seems
to be more in line with the rest of the example.
Leaving `--watch` as a double dash option to minimize the change,
though it could be either way, since the follow up example uses
the single dash version of both.
