[PATCH v2 0/2] guides: keep Documentation/Makefile and command-list.txt in sync

Documentation/lint-manpages.sh was expanded with a new test ensuring that command-list.txt also includes all non-command manual pages (concept guides and interface manuals).

Based on kh/doc-datamodel.

Changes in v2:

* [1/2]: Use command-list.txt as the area identifier.
* [2/2]: Protect variables againtst whitespace breakage per review comment.

Tuomas Ahola (2):
  command-list.txt: add gitformat-loose(5) and gitpacking(7)
  lint-docs: check the guide list in command-list.txt
