Subject: [PATCH v2 0/3] List all guides in git(1)

From: "Philippe Blain via GitGitGadget" <[email-masked]>

Changes since v1:

 * Incorporated Junio's suggestion to reduce duplication.

v1: This series adds a list of the guides to git(1).

The first commit adds the misssing guides 'gitcredentials' and
'gitremote-helpers' to command-list.txt. The only missing guide after this
change is 'gitweb.conf', but I think this one is obscure anough, and already
linked to in 'gitweb.txt', that it does not matter much.

The second commit drops the usage of 'common' and 'useful' for guides. This
was suggested as one of two ways forward by Duy in [1] but was not commented
on. I'm CC'ing the people that were CC'ed on that message.

The third commit tweaks 'Documentation/cmd-list.perl' so that it also
generates a list of the guides, which gets included in 'git.txt'. I chose to
put this list just after the end of the list of commands.

     +    `Documentation/cmd-list.perl` script to generate a file `cmds-guide.txt`

     -    a file `cmds-guide.txt` which gets included in git.txt.
     +    Instead of hard-coding the list of command categories in both
     +    `Documentation/Makefile` and `Documentation/cmd-list.perl`, make the
     +    Makefile the authoritative source and tweak `cmd-list.perl` so that it
     +    receives the list of command categories as argument.
      
          Also, do not hard-code the manual section '1'. Instead, use a regex so
          that the manual section is discovered from the first line of each
