When hg is invoked without parameters, the short list help is displayed.

When hg is executed without parameters ( or hg is executed with the
'help shortlist' command ) the short help list is displayed.
If the 'help' command is passed on the commandline the full help list
is displayed.
In both the cases if the switch '-v' is passed, the help contains also
the aliases of the short/full commands list and the global switches.
