[PATCH v3 2/4] generate-cmdlist.sh: parse common command groups

["Sébastien Guimmara" <sebastien.guimmara@gmail.com>]

Teach generate-cmdlist.sh to parse common command groups
found in command-list.txt in the form

common-3_worktree ('3_worktree' being the group identifier)

Extract the $grp variable, in addition to the previous $cmd,
and inject it as a third field in the cmdname_help struct:

{"add", N_("Add file contents to the index"), "3_worktree"},

So that when 'git' is called, we can display common commands
grouped by theme instead of a less useful alphabetical order.
