Re: [PATCH 6/7] walk PATH to generate list of commands for "help -a"

Rationale?

There are two cases execv_git_cmd() runs "git-that" from a non standard place, if we take your [PATCH 4/7].

 - If there is a directory that contains a location that used to
   hold an old installation of git-* commands (some of which may
   have been removed in the latest git) and if the user has that
   directory on PATH, we would run obsolete git subcommand from
   there.

 - If the user has a custom command "git-that" in $HOME/bin/
   that is outside GIT_EXEC_PATH, the new subcommand "that" can
   be used as if it is part of the official git.  This is an
   improvement [PATCH 4/7] would bring in.  We allow this
   already for scripts anyway, and the patch is merely making
   the behaviour of the execv_git_cmd() consistent with it.

It may be nicer if the user can somehow tell from the output if each of the command is from the standard set (i.e. on GIT_EXEC_PATH or built-in), or from a non standard place (either custom command as intended, or an unintended obsolete leftover).
