[PATCH v2 2/3] git help: group common commands by theme

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

Extract the $grp shell variable from command-list.txt (eg: 
'common-3_worktree') and add
this value to the output:

before/after:
{"add", N_("Add file contents to the index")}
{"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.
