[PATCH v10 1/5] command-list: prepare machinery for upcoming "common groups" section

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

From: Eric Sunshine <sunshine@sunshineco.com>

The ultimate goal is for "git help" to classify common commands by
group. Toward this end, a subsequent patch will add a new "common
groups" section to command-list.txt preceding the actual command list.
As preparation, teach existing command-list.txt parsing machinery, which
doesn't care about grouping, to skip over this upcoming "common groups"
section.
