[PATCH V3 0/5] Git help option to list user guides

[Philip Oakley <philipoakley@iee.org>]

This is the re-roll of $gmane/217384. The series seeks to provide a help
option that will list the common git guides, and how to access them.

The series is rebased on top of V1.8.2 

Since V2, the OPT_BOOL is now used instead of OPT_COUNTUP.
The git_more_info_string has been further updated inline with Junio's
suggestions, and re-spaced so that command example are not split over
line ends.

Junio's suggestions in $gmane/217354/focus=217355 have been included.
Junio also asked about the `if (!argv[0])` test which is, correctly,
performed _after_ the -a and -g options are taken, as they overide any
remaining arguments.

The list of guides is spaced out in the same manner as the common
command list.

Philip Oakley (5):
  Show help: -a and -g option, and 'git help <concept>' usage.
  Help.c use OPT_BOOL and refactor logic
  Help.c add --guide option
  Help.c: add list_common_guides_help() function
  Help doc: Include --guide option description
