[PATCH 05/13] Help.c: add list_common_guides_help() function

[Philip Oakley <philipoakley@iee.org>]

Re-use list_common_cmds_help but simply change the array name.
Candidate for future refactoring to pass a pointer to the array.

Do not list User-manual and Everday Git which not follow the naming
convention, nor gitrepository-layout which doesn't fit within the name field size
