[PATCH] stash show: use default pretty format

[PATCH] stash show: use default pretty format

[Tay Ray Chuan]

By default (ie. when stash show is invoked without any arguments), the
diff stat of the stashed changes is displayed. Let git-diff decide the
default pretty format to use.

This gives git more consistency, as users who have set their
pretty.format config would naturally expect `git-stash show` to display
the diff in the same pretty format as the other diff-producing procelain
like git-log and git-show.

A handful of issues:

 - The stash entries, unlike the usual commits you store on branches and
   inspect with "show", are designed to be quick escapes for emergency
   interruption, and "--stat" is a good default to remind the user what
   she was working on before she was interrupted _without_ scrolling the
   top of the screen away by showing the full diff.  Careful design
   decisions far outweigh mechanical application of "consistency for the
   sake of consistency".

 - What does "pretty.format" has anything to do with "stash"?

 - If it does, why doesn't the script read from it?

 - How does this justify the UI regression for people who are used to the
   good default "--stat" they have been seeing?
