[PATCH 0/1] Add stash entry count summary to short status output

[Sonny Michaud <michaud.sonny@gmail.com>]

this patch adds a header in the same style as the one provided by the --branch option when the user supplies both --show-stash and --short.  My attempt at creating a new test is broken[1], and I assume my changes could (and, likely need to) be improved.  Any assistance would be greatly appreciated; I just wanted to get started by hacking first and asking questions later!                         
                                                                               
Thanks,

Subject: [PATCH 1/1] status: learn to show stash in short output               

This patch extends the functionality of the recently introduced                
--show-stash option to the status command, providing a header similar to       
the one displayed when using the --branch option.
