Re: [PATCH] help.c: Pull cmd_version out of this file.

Promote cmd_version to a builtin, by moving it to its own file

Could you explain further?  If the goal is "one command per source
file", then we already violate that in a number of places:

 - "git blame" and "git pickaxe" are both cmd_blame() in
   builtin/blame.c.

 - "git whatchanged", "git show", "git reflog", and "git log" are
   separate builtins in builtin/log.c.

 - etc

What does this make easier?
