[PATCH] Split external diff command interface to a separate file.
With this patch, the non-core'ish part of show-diff command that invokes an external "diff" comand to obtain patches is split into a separate file. The next patch will introduce a new command, diff-tree-helper, which uses this common diff interface to format diff-tree and diff-cache output into a patch form.
