Re: [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"}

When 'git help' is called, the displayed commands can be grouped by theme
instead of a less useful alphabetical order.
